The story of a tontine—a trust created for a clutch of privileged school-boys that will go to the last man standing—should have the same breakaway, mean-spirited greediness of, say, It's a Mad, Mad, Mad, Mad World (Stanley Kramer you wouldn't think of being able to do a comedy, either, but look at that result!), Those Magnificent Men in Their Flying Machines, or The Great Race, but instead has a leaden lethargy sometimes punctuated by awkward transitions, ill-timed (and rather unnecessary) close-ups, and the frequent appearance of title cards (to explain something the direction does not adequately provide) in a black-out format that recalls silent movie transitions. It's Forbes imitating Richard Lester, and as slap-dash as the latter could be at times, he at least could tell a story, and give it the momentum so it would never flag.
Great cast, though: Michael Caine, Peter Cook and Dudley Moore, John Mills and Ralph Richardson; Peter Sellers has an extended cameo as a fraudulent doctor that starts slowly but finally picks up a weird head of steam. And there's an odd love story between Caine and Forbes' actress-wife Nanette Newman that seems unconvincing. The screenplay is by Larry Gelbart and Burt Shevelove, who wrote the book for the Broadway musical "A Funny Thing Happened on the Way to the Forum" (Lester's film of which was released the same year—coinicidence?) John Barry's galumphing score works overtime to make it frothy, but this is one granite souffle. What is missing is whimsy, rather than desperate manicness, and it fortunately is found in Sellers' work, and in the odd performance of Wilfrid Lawson as the harried (not that you'd know) butler, Peacock.
