Olsen-banden

Despite being the first, this is neither the best of the movies, nor well-known enough to justify it's inclusion in the citizenship test,. But it's not bad. The formula is already in place, as are most of the characters (I like to imagine that in the next movie the oldest son had moved out, taking his little sister with him, leaving only Børge) but the heist is less Storm P (or Rube Goldberg if you're not Danish) than would later become the norm and there's a strong element of bawdy romp.
