"Was tun wenn's brennt?" is German, and it shows. The film wants to be a hip drama/comedy about former Berlin anarchists who have to get together for one last time when a bomb they built in 1987 suddenly goes off, but somehow, it's all lacking in finesse a bit.

The old comrades in arms against capitalist oppression have turned into single mothers, ad execs, and lawyers, except for Hotte (Martin Feifel) and Tim (Til Schweiger), who kept the anti-imperialist flame alive and now have to win their old friends and ex-lovers back to save them from their own past. The formula is executed with such efficiency that you can't help being entertained, right? Right? Jawohl!

There's bad German rock music on the soundtrack and star Til Schweiger ("S.L.C. Punk," "Driven") looks too buff for his role. Still, first time director Gregor Schnitzler's film is not unpleasant, if only for the sponti nostalgia for those who fondly remember the riots during Reagan's visit to the divided city. Their answer to the title's question? "Let it burn!"
