Giliap is a 1975 Swedish drama film directed by Roy Andersson, starring Thommy Berggren as a man who takes a job as a waiter at a hotel. It was a financial and critical failure, and it led to Andersson's not making another feature film for 25 years. Andersson admitted that the film contains flaws, and he said that the main reason for them was that he was not completely in control of the production, and therefore he had to compromise in several scenes.
