The Man Who Quit Smoking Swedish Mannen som slutade rka is a 1972 Swedish comedy film directed by Tage Danielsson, starring Gsta Ekman, Grynet Molvig, CarlGustaf Lindstedt and Gunn Wllgren. The film is known as a Hassetagefilm and is a great cult classic in Sweden.
Tage Danielsson originally came up with the idea for this movie when he himself decided to quit smoking. If he made a movie about the subject he thought it would be to embarrassing if he ever started again. Another inspiration was Dante Alighieris Divine Comedy. The main character is named Dante and his loved one is called Beatrice, just as in Dantes Inferno.
