The Wrong Box (1966 Bryan Forbes)

Messy, unsuccessful movie about brothers John Mills and Ralph Richardson and who will live longest and collect an inheritance. Much foolery ensues, with relative Michael Caine falling for 'cousin' next door, the anodyne Nanette Newman, whilst Peter Cook and Dudley Moore attempt to win the money, delivering bodies to the wrong house etc.

My favourite performance is of the butler Peacock by veteran Wilfred Lawson, who died the same year.

With guest stars at every turn - Leonard Rossiter, Tony Hancock, Irene Handl, Peter Sellers, John le Mesurier.

Written by the normally reliable Larry Gelbart, and Burt Shevelove, inspired by Robert Louis Stevenson, with pointless intertitles. (Though quite liked Richardson's factmeister, who won't stop talking.) Even John Barry's score is atypically twee. Photographed by Gerry Turpin. Not sure on reflection that Forbes has ever made a good film. Yes he has, Whistle Down the Wind (and, I think, though it's been a while, The L Shaped Room).
