In page Autumn Sonata:

"

Due to his battle with the Swedish tax authorities at the time,[n 1] Ingmar Bergman produced Autumn Sonata through his West German company, Personafilm GmbH, with main financing from Lew Grade's British ITC Film, and shot the film in an old film studio outside Oslo in Norway.[1] Although formally a German production (with the German title, Herbstsonate, being the official original title), the dialogue is in Swedish, most of the crew and actors were Swedish,[2] and the world premiere was in Stockholm.[3]
