Lupin the Third: The Legend of the Gold of Babylon
What they share
Both films are directed by Seijun Suzuki, and they sit in Crime territory. If that's the register that drew you to Take Aim at the Police Van, the second film will land in a comparable space — through a different lens.
What Lupin the Third: The Legend of the Gold of Babylon is
Here's a film that wants to be all things to all people, and nearly succeeds. Lupin and his gang pursue some very old gold while dodging rival gangs and the ever-persistent Inspector Zenigata. It's a charmingly absurd lark, if nothing else.
