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.

Phil Richards, says modestly, that he came across this location by accident but we must award some praise on him for it has outstood with us for 11 years, the spot having become increasingly overgrown during the past 20 years. In fact it is travelling down Littleworth Road (north of Taplow), looking towards the junction of Dropmore Road (bending left) and Wooburn Common Road (RH turn). (RL)

Phil took this comparative shot for us and tells us that the site, having been 'tidied up' reveals the building straight ahead which is Oak Lodge the NE gatehouse to the Dropmore Estate, with the entrance gates just slightly to the left. The thatched building behind the hedge on the right being Dropmore infants school. (RL)
