Bill Bergson Lives Dangerously (original Swedish name: Mästerdetektiven Blomkvist lever farligt) is a 1957 Swedish film about Kalle Blomkvist, directed by Olle Hellbom. It is based on the novel with the same name, written by Astrid Lindgren. It was recorded in Trosa, Södermanland. There are differences between the book and this film: The murderer wears checkered trousers instead of green gabardine trousers. The mansion house has been changed to a "ghost castle". In the end, the murderer tries to escape with his car, but here he instead escapes with a boat but can't because Kalle, who also is on the boat, takes the revolver from him and shoots holes in the boat.
