A favourite of mine. Sound editing is really terrible though. During train wreck scene, there's a pitiful 4-5 second track of a woman screaming that's been looped over and over again underneath the dialogue. Newman and Caine were tremendous in taking the mickey out of sexually repressed British culture, and their farcical romantic Victorian slow-mo sequence is my favourite!
This kind of production always makes me wonder whether the audience was really doubling up when it was theatrically released. THE WRONG BOX is a slapstick comedy (with inserts) that could have been shot in the 20's. It's really funny at times (the train scene, Peter Sellers as Dr. Pratt) but you have to appreciate British humour... Recommended.
