Rötmånad (American title: Dog Days, British title: What Are You Doing After the Orgy?) is a Swedish dark comedy film from 1970 directed by Jan Halldoff.
In the Stockholm archipelago lives the barber Assar Gustafsson (played by Carl-Gustaf Lindstedt) peacefully with his 17-year-old daughter Anna-Bella (played by Christina Lindberg). One day Assar’s wife Sally (Ulla Sjöblom) comes back after five years of absence and she starts up a brothel with the young girl as the main attraction.
The film contains a lot of nudity and violence, but also a lot of humor, and has achieved cult film status in Sweden. In 2014, SF released it on DVD as part of Fyra klassiska filmer av Jan Halldoff box set.
