Bill Bergson Lives Dangerously (original Swedish name: Mästerdetektiven Blomkvist lever farligt) is a 1957 Swedish film about Bill Bergson (in Swedish as Kalle Blomkvist), directed by Olle Hellbom. It is based on the novel with the same name, written by Astrid Lindgren, and 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 novel, the murderer tries to escape with his car, but in the film he instead escapes with a boat but can't because Kalle, who is also on the boat, takes the revolver from him and shoots holes in the boat.
