Die Ruckkehr Der Zeitmaschine on AllMovie

Based on a novel by Günter Kunert, Rückkehr Der Zeitmaschine is a crowded, clichéd sci fi comedy set in 1925 about a doctor who discovers a "time machine" in the back room of an antique shop and then gathers his friends together to decide what to do with it. They eventually plot to test the machine with a particular factory assistant -- the trick is to get him to agree without letting him know about the dangers involved.
