Claes Ljungmark is a durable Swedish actor who has spent far more time working than being talked about. Work has kept arriving for 45 years, which is its own kind of achievement. The role of Mats Hasselqvist in 'Borg vs McEnroe' is the one that keeps being brought up. 'The Keeper of Lost Causes' is another title that gets mentioned. Viewing habits have changed more than once since the first credit. Drama has been the most frequent territory.
