I originally saw a trailer for this film on another film that I rented, but; I can't for the life of me, remember the name of the movie that I rented or the name of the film in the trailer. Anyway, the film I am trying to find is about a bunch of 60's radicals who plant a bomb in a German govt. building. The bomb turns out to be a dud and does not go off as planned until about 30 years later after the building has been converted into a regular office complex. The 60's radicals have now all become the "establishment" that they once so despised and now must cover their tracks. The movie is about 3 or 4 years old and it is a black comedy. That is all that I can remember about it. If someone could help me I would really appreciate it. Thanks.
