Lost! is a Canadian drama film, directed by Peter Rowe and released in 1986. Based on the book of the same name by Thomas Thompson, the film centres on three survivors of a shipwreck, two brothers and one of their wives, whose chances of survival are threatened by the more religious brother's conviction that they must trust in God to save them rather than making any effort of their own. The film stars Kenneth Welsh as Jim, Michael Hogan as Bob, and Helen Shaver as Linda.
