Apart from the costumes there's not much of the Batman we know today in the Caped Crusader's first movie outing. It was released in the midst of WWII, so instead of Jokers or Penguins we get a devilish Jap, played with relish by J. Carrol Naish. He's the best thing about this otherwise mediocre effort which nevertheless stands head and shoulders above most other serials of the day.
