Rolf Peter Kahl is one of the more persistent actors of his generation who has rarely been away from the screen for long. If the filmography has a home genre, it is comedy. The career now covers more than 35 years. The film 'Berlin Calling' accounts for more of the public profile than anything else does. Among the rest of the work, 'A Coffee in Berlin' stands out. The filmography reaches back well before the best-known title.
