Without a Clue

Dr. John Watson (Kingsley) is secretly a crime-solving genius. But to protect his reputation as a physician, he hires bumbling, boozy, out-of-work actor Reginald Kincaid (Caine) to play the part of his fictional creation, Sherlock Holmes. The charade works until Watson mysteriously disappears, forcing the baffled, seriously inept Holmes to crack the biggest case of Watson's career on his own! (official distributor synopsis)
