Sleuth (1972)
Based on a play by the same name, Sleuth stars cinematic legends Michael Caine and Sir Laurence Olivier, as two men that perpetuate an insurance scam, that involves a fake robbery. As it slowly grows out of control due to intrigue and betrayal, you see both characters start to fall apart. With a lot of misdirection and clever tricks, this film keeps you guessing until the very end, and doesn’t need to resort to cutaways to tell the story; the actors to a marvellous job themselves.
