They've Got Knut (2003)

Set in the early '80s, a time when a new wave of leftist political consciousness and activism had swept German youth (and was just about to disappear as quickly as it arrived), this satiric comedy follows a young couple, Ingo (Hans-Jochen Wagner) and Nadja (Valerie Koch), as they travel to Austria for a weekend of skiing near her parent's luxurious chalet. While Ingo and Nadja have an open relationship, he thinks its time that they commit to one another exclusively, and is hoping this weekend will convince her this is a good idea. However, their privacy is interrupted when several guests arrive -- friends of Nadja's brother Knut (Ingo Haeb), a noted political activist, who, unbeknownst to her, has also planned a ski weekend. As the guests await Knut's arrival, they get the unpleasant news that he's been arrested during a demonstration; several propose that they should come to his aid, while the majority decide instead to go skiing as a way to pay tribute to his commitment to the cause.

Unfortunately the movie They've Got Knut is not yet available on HBO Max.
