Deathtrap. Michael Caine is a once successful playwright desperate for another hit after a string of flops. So desperate, in fact, that when a former student (Christopher Reeve) send him his first play, which he thinks is so good it will be a massive success, he decides, much to the disbelieving horror of his wife (Dyan Cannon), to murder him and steal the play for himself... or does he? Nothing is quite as it seems in this hugely entertaining twisty turny tongue in cheek early 80s comic thriller. Haven't seen this for decades, but still great fun.
