MINISERIES PREMIERE: Evelyn Waugh’s novel Brideshead Revisited inspired one of the most celebrated miniseries ever made, the 1981 version starring Jeremy Irons. Now, from Acorn TV, comes another import devoted to a work by the same author. Decline and Fall, though, while it’s set in the same gorgeous posh British estates and institutions, is a lot more comic and playful an approach. It’s Waugh’s first novel, and he delights in playing with his caricatured characters – which, in turn, allows the TV show’s actors to play with almost giddy abandon. Jack Whitehall plays the naïve yet resourceful young man at its center, but Decline and Fall is stolen by two more familiar faces: David Suchet, once the great Poirot, now playing a silly and stuffy headmaster, and Eva Longoria, who plays Margo Beste-Chetwynde – a privileged American married into British society and then widowed, as though she’s a costumed cougar sent through time straight from Desperate Housewives.
