Ralph Richardson and John Mills star as two elderly brothers who are the last surviving members of a Tontine - a bizarre lottery in which the last man still alive scoops a fortune. While the two old buffers steadfastly refuse to die, some of their relatives decide to sort things out once and for all. While ineffectual Cousin Michael (Michael Caine) and ever-so-slightly demented Cousin Julia (Nanette Newman) fumble their way into romance, venal Cousin Morris (Peter Cook) and lothario Cousin John (Dudley Moore) plot to get their sweaty hands on the fortune. Unfortunately, when they accidentally mistake the corpse of the infamous Bournemouth Strangler for dear Uncle Joseph and ship him in a barrel back to London, they set off a farcical chain of misunderstandings with hilarious consequences. Further confusion is provided by Peter Sellers as the cat-obsessed Dr. Pratt and Tony Hancock as a detective as everyone tries to work out who's really alive and entitled to the money. With an all-star cast featuring some of Britain's best-loved comedy talents, The Wrong Box is a truly black comedy farce in the best traditions of British cinema.
