Hallo, Taxi!(1974)

The story of a philanderer behind the wheel of a cab, who gets into a series of hilarious but also adventurous situations, was based on the actual experiences of Berlin cab drivers. It is an entertaining portrayal of how the main protagonist, Eddy, is to be cleverly dissuaded from his dashing bachelor life. Gaby and her grandpa come up with a few ideas. This is necessary, because Eddy may be a proper cab driver, but in his private life he knows no rules when it comes to winning over pretty girls.
