Deathtrap (Blu-ray)

If you were a famed mystery playwright with a devastating string of recent flops, what would you do for a can't-miss thriller script? Beg for it? Pay for it? Or would you kill for it? You would if you were Sidney Bruhl, the leading character in Ira Levin's dazzlingly funny, deliciously scary, Broadway-smash-turned-movie-hit Deathtrap. Michael Caine starts as Bruhl and Christopher Reeve stars as Bruhl's one-time student, who's written a play so flawless "even a gifted director couldn't ruin it" ...and who requests Bruhl's production help. And Dyan Cannon is Bruhl's loving wife, who doesn't want the student helped to an early grave. Sydney Lumet directs Deathtrap's hairpin twists with such drop-dead wit and delightful dread that you'll stop laughing only long enough to gasp in surprise.
