nothing more enjoyable for me than a who dun it or suspense tale that keep you guess throughout a to how the whole thing will end . and that precisely what happen in deathtrap and base on a chilling play by ira levin ( rosemary baby ) . and in it and michael caine and christopher reeve get to do the kind of stunt that caine and laurence olivier pull off in sleuth with just about as much skill and a many puzzle a ever exist in that extraordinarily clever play . but because it mean to scare you and surprise you and and keep you guess a to the outcome and it difficult to write a review about the plot . let just say that what we know in the beginning be all you have to know about the film for the present . michael caine be an insanely jealous playwright whose late play have fail miserably . when a young aspiring writer christopher reeve send him the manuscript of his play and caine realizes that pass it off a his own would solve all his problem and get his reputation back . from that point on and it a matter of fun and game for the audience a ira levin story unwinds and manage to trump agatha christie for the number of twist . caine and reeve play off each other brilliantly and each bring a certain dynamic tension to the tale as well a some humorous touch that come from a script that lace drama with humor . sum up represent well worth see but not everyone be please with the end .
