He Can't Stop Doing It

He Can't Stop Doing It (German: Er kann's nicht lassen) is a 1962 West German mystery film directed by Axel von Ambesser and starring Heinz Rühmann, Rudolf Forster and Grit Boettcher. It was loosely based on the Father Brown stories by G. K. Chesterton, Rühmann reprising his role from the 1960 film The Black Sheep. It follows in the post-war tradition of German krimi films, similar to the series of Edgar Wallace adaptations popular at the time.

The film's sets were designed by the art directors Rolf Zehetbauer and Herbert Strabel. It was shot at the Bavaria Studios in Munich and on location at Anif Palace near Salzburg, doubling for Darroway Castle in the film. Other filming took place in Ireland itself.
