Can you help:
If you have any information regarding this production, the locations or, even better, some comparison shots please contact us. Images submitted must be in Landscape orientation, as would be seen on the cinema screen, not Portrait.
We are aware that there are films on the site that were added when the criteria for the inclusion of locations was very different from today and, as a result, there may be scenes missing from some productions. Please do not forward additional screen captures to us but bring the detail to our attention, for we do, and are, 're-addressing' these older entries as time allows.

Passing his nursing Sister Rogers (Patricia Dainton) who is just arriving.
Parking is still permitted.
- Capture 3
- 27 Jul 2016
He walks along the Embankment. This location was seen in 'What a Crazy World'.
Comforting to see that it is all very much the same.
- Capture 4
- 27 Jul 2016
He is passed by an ambulance that draws to an halt. In the background the Anglo-Belgian Memorial. Embankment, London.
The crossing has gone and a cycle lane is very much in the making.
- Capture 5
- 27 Jul 2016
A nurse jumps out saying that they had come from the hospital and could he get in and look at the patient. The right hand side of the Anglo-Belgian Memorial to the left and Savoy Hotel background left.
Could that be the same tree?
- Capture 6
- 10 Oct 2020
After performing an emergency operation at an unknown location Mark is drugged and dumped elsewhere and awakes to find himself on a park bench. Now part of Walton-on-Thames Tennis Club with 31 Hersham Road, Walton-on-Thames, Surrey in the background.

Anne Poole send us this shot of the same place today adding that Is not part of the Tennis Club but a little council owned public park. The benches are now absent but the recessed areas that they sat in are still there. In the case of the bench in the still, it’s become another entrance.
- Capture 7
- 27 Jul 2016
At the end of the day he arrives home. Maitland Court, Gloucester Terrace, London W2. Also seen in 'Whispering Smith Hits London', 'Mantrap', 'Song of Paris' and 'Flannelfoot' and, as David Richards spotted, 'The Saint's Return'.
No longer can a taxi drop you there.
- Capture 8
- 27 Jul 2016
After a friend is shot in his flat Mark goes with Sister Rogers to the home of a patient Mrs Terry who has a clue as to where he might have performed the operation. The old offices of J E Purdie & Son, 34 Bridge Street, Walton-on-Thames in the background. Also seen in 'Glad Tidings', 'Madame Louise', 'Morning Call', 'The Naked Truth', 'Trouble with Eve' and 'The Sleeping Tiger'.
A recent shot from Stephen Dean for 'The Sleeping Tiger' adequately covers this now much changed corner.
- Capture 9
- 27 Jul 2016
They arrive at her home only to find that she has been murdered. Bridge Street near Nettleford studios in Walton-on-Thames. Also seen in 'The Sleeping Tiger'. But Mark believes he finds the clue.
The recent shot from Stephen Dean covering an almost identical shot in 'The Sleeping Tiger' reveals the sad change of scene.
- Capture 10
- 27 Jul 2016
With the “information” he drives off in search of the house and arrives in High Street, Cookham, Berks.
Little has changed except the volume of traffic.
- Capture 11
- 27 Jul 2016
And draws up outside Bell & The Dragon to ask for directions. High Street in Cookham, Berkshire.
Not so easy to just "draw up" these days.
- Capture 12
- 25 May 2018
He passes a house and crossroads where he has to decide which direction to go. Phil Bailey came across the junction of Winter Hill, Stonehouse Lane and Gibraltar Lane near Cookham.

Phil also provides this modern view adding "As with so many locations, the trees have grown a good deal in the intervening 60+ years; the house is still there but completely obscured."
- Capture 13
- 27 Jul 2016
Without any success he returns home where nurse Lisa Durand (Lisa Daniely) who was present at the operation is waiting for him. Maitland Court, Gloucester Terrace, London W2. Included again because I like to enjoy the properties that were demolished to make way for the building of the hotel.
See what I mean?
- Capture 14
- 27 Jul 2016
The patient has had a relapse and requires immediate attention. Once again Mark is taken at gunpoint by ambulance. Gloucester Terrace, Maitland Court out of shot to the left and Lancaster Terrace at the rear. The same terrace seen in 'Whispering Smith Hits London'.
Part of our purpose is to record change.
- Capture 15
- 'Now' required
The ambulance draws up at the house. Unknown location but probably Warren House, Warren Road, Kingston-Upon-Thames but a personal visit is necessary to establish the exact part.
- Capture 16
- 'Now' required
On the pretext of needing essential medicine he persuades his captors to take him to the hospital the following morning. View from the house. Probably Warren House, Warren Road, Kingston-Upon-Thames, a personal visit is necessary.
- Capture 17
- 27 Jul 2016
The ambulance arrives at the hospital. Dean Ryle Street, London SW1 Page Street off to the right and left.
More modern structures continue to evolve.
- Capture 18
- 27 Jul 2016
Mark informs the police who make arrangements to follow the ambulance to where the diplomat is being held. Page Street with Thorney Street, London SW1, now infilled and the home of MI5. The arch is still visible from the front elevation.
The rear entrance to Thames House, Millbank.
- Capture 19
- 27 Jul 2016
The police close in. Horseferry Road on the corner with Dean Ryle Street. The obelisk with pineapple topping on Lambeth Bridge can be seen just beyond the left hand building.
A more cluttered foreground but the pineapple is just visible.
- Capture 20
- 27 Jul 2016
The rest of the force approach the ambulance. Dean Ryle Street, looking towards St John’s Smith Square. But this turns out not to be the ambulance they were expecting.
A better view of St John's, Smith Square at the end.
- Capture 21
- 27 Jul 2016
Mark advises the police of the aspects of his journey to the hospital he memorized with a view to establishing the journey path. The first, a clock with a “cracked chime”. All Saints Church, Market Place, Kingston upon Thames.
That tree has sure grown.
- Capture 22
- 27 Jul 2016
Having found this location the police set off with Mark. Market Place, Kingston-upon-Thames. The Market Place was also seen in 'Marriage of Convenience', 'The Lost Hours' and 'The Yellow Teddy Bears'.
No such excitement during my visit.
- Capture 23
- 27 Jul 2016
Now pedestrianised. facing High Street, Kingston-upon-Thames.
Largely re-developed.
- Capture 24
- 08 Jun 2020
“Two sets of traffic lights”, the first set. Richmond Road approaching the junction with Lower Kings Road, Kingston-upon-Thames.

John Saunders enlisted the help of his wife for a team effort to capture the same scene almost 70 years on. They regret that they were unable to await a No 65 bus to match but are able to fill in with the non apparent changes. The building ahead on the left just beyond the junction was a doctor's surgery until a few years ago and probably was back in 1953, but is now a children's nursery. The houses beyond had advertising hoardings even back then. The brick gateposts to the right of shot still exist.
- Capture 25
- 08 Feb 2019
The second set. Fairfield West facing Knights Park.

Adam has kindly sent us this shot of the same location showing some quite significant changes to the road usage.
- Capture 26
- 07 Jun 2017
“Queer whirring sound, That’s it!" St. Petersburgh Mews, London W2
Nowhere near Kingston as the director would have us believe. Gentrified in the intervening years.
- Capture 27
- 27 Jul 2016
“A bridge”. Springfield Road, Kingston upon Thames.
That old gnarled tree still remains but the bridge has been closed to traffic.
- Capture 28
- 05 Feb 2023
“A steep hill” Peter Bywaters advises that this is Upper Brighton Road, Surbiton travelling towards Victoria Road.

Peter send us this photograph of the location today in support adding that since the film was made in Mountcombe Close on the right has been built, he believes around 1963. Further, he says, in the distance left of the screen capture, is a bus stop which a motorcyclist is just passing, beyond that on the opposite side of the road are what appear to be two conifer shaped trees, the bus stop position and two trees can still be seen today.
- Capture 29
- 17 Apr 2018
“The drive is on the right” Kingston Hill just before the turning to Warren Road.

All very much the same save for road markings.
- Capture 30
- 17 Apr 2018
They turn off the main road, park at the entrance gateway and “spread out!”. The entrance to Warren House, Warren Road, Kingston-upon-Thames. Not sure if that gate post is still there.

Other pictures would suggest that the entrance drive has been moved but the post cappings have been retained. Taken from the road as the General Managers permission would be required to take shots within.
- Capture 31
- 17 Apr 2018
Mark and Inspector Austin (Ballard Berkeley) approach the house. Warren House, Warren Road, daylight view.

Warren House from the road suggesting that the entrance drive has been moved to the right.
- Capture 32
- 'Now' required
Those turned stone mullions are very identifiable.
- Capture 33
- 17 Apr 2018
There is nobody there and the house has been cleared. The police make off. The front of what is now an hotel.

Not quite the correct angle as extracted from a shot taken from the road.
- Capture 34
- 17 Apr 2018
Leaving Mark to fend for himself and an even better view of the house

Once again, taken from the road and suggesting that the entrance drive has been changed.
- Capture 35
- 29 Jul 2016
Wade (Sydney Tafler) takes Sir Oliver Peters (James Raglan) and nurse Lisa Durand (Lisa Daniely) to a secret location. The building on the left and The Mitre public house on the right confirms this as looking towards Craven Terrace from Brook Mews North, London W2.
This is taken from what is now Brook Mews North looking towards Craven Terrace and Lancaster Mews. On the far right, The Mitre pub, seen in "Scoop" and "Connecting Rooms", remains as does the lower row of buildings on Lancaster Mews, including Sheila's Sandwich Bar, beloved to cabbies. But there have been some dramatic changes including road realignment and a housing block (out of sight to left) which hindered a more accurate angle. SJ
- Capture 36
- 28 Feb 2017
Looking north-east towards the junction of Gloucester Terrace and Bishops Bridge Road in W2 with Caernarvon House on the Hallfield estate to the left and the spire of Holy Trinity church rising above Gloucester Terrace to the right. Identified by PW.
Caernarvon House is hiding behind the tree on the left. (PW)
- Capture 37
- 05 Apr 2016
Harrison (Michael Golden) who was driving the van arrives at where Sir Oliver Peters and his captor Wade as well as Nurse Lisa are being held until Lisa says she “wants out” and escapes to the roof. The rooftop of Windsor Court looking down Moscow Road, London W2 at the intersection with Ilchester Gardens to the right and the Greek Orthodox Church and St Petersburgh Place with St Matthews, Bayswater to the left.
I am afraid that I could not rise above ground level.
- Capture 38
- 05 Apr 2016
Wade manages to shoot at her whilst she runs down the fire escape, a crowd gathers and she is taken away by ambulance. Moscow Road, London W2 looking at Caroline Place.
Since the in-fill dvelopment we are now looking at Poplar Place, but The Kings Head remains.
- Capture 39
- 23 Feb 2016
Mark, with the police, saves the day, Sir Oliver Peters is saved and the ship that was to take him from these shores sails without him. Tower Bridge, from the Pool of London.
Sir Peter would have to depart by River Bus these days.
