After Magritte is a rip-roaring comedy about ordinary people in a most bizarre situation: a senile woman obsessed with the tuba may or may not be the mother of anyone in the room; a neurotic police inspector may or may not have a search warrant for an unidentified tortoise; an argumentative couple may or may not have seen a man covered in shaving foam wearing the kit of West Bromwich Albion. Stoppard's play is a sophisticated romp into the delightful absurdity of sixties suburbia, proving that splendid absurdity doesn't just emerge from the mundane, but thrives on it.
