Ugler i mosen

Ugler i mosen is a 1959 Norwegian mystery and adventure family film directed by Ivo Caprino. The title, which literally means 'Owls in the Moss', is based on the idiom det er ugler i mosen 'I smell a rat; there is mischief afoot'.

The film was written by Caprino as an adaptation of Finn Havrevold's children's book Marens lille ugle (Maren's Little Owl). The leading role was played by 12-year-old Grethe Nilsen, and the film also featured Sverre Hansen, Turid Balke, Kjetil Bang-Hansen, Egil Hjorth-Jenssen and Aud Schønemann.

Animation figures also played central roles in the film.
