Over at Alex on Film I’ve been watching some film versions of Anthony Shaffer’s play Sleuth. Or at least the 1972 Laurence Olivier-Michael Caine Sleuth and the 2007 Michael Caine-Jude Law Sleuth, with 1982’s Deathtrap (Michael Caine and Christopher Reeve) sandwiched in-between. Deathtrap is actually based on Ira Levin’s play, but it also clearly derives from Sleuth, and may even be closer to Shaffer’s play than the 2007 movie, which was written by Harold Pinter.
