La Cage aux Folles
(1978) was based on a stageplay, and went on to become an enormous hit, spawning two sequels, a Broadway musical, and the American remake. It concerns a gay couple, Renato Baldi (Ugo Tognazzi) and Albin Mougeotte (Michel Serrault), involved in the 'drag' industry, and the mild social quandary that arises when Baldi's son announces his engagement. The flamboyant pair have to tone things down a notch to convince as straight in front of the their future daughter-in-laws's conservative parents.
Mike Nichols directed the starry US remake, which arrived almost two decades after the French movie. Robin Williams and Nathan Lane are the campy couple, and Gene Hackman is the grouchy potential father-in-law. Williams opted to play the straight(er) man, allowing Lane to run with the more OTT histrionics, before everything descends (inevitably) into farce.
The story is uprooted to Miami Beach, and a few Stephen Sondheim songs are thrown in for good measure, but this redo actually captures much of the charm and humour of the original.
