De La Tour des Héros.
From Animato
"This show has a lot of stupid stuff in it like Batman finds a toothpick and figures it's Bullock," said producer Bruce Timm. "Duh! But it's one of those shows that works purely on a visceral level. It's well-staged and the animation is good. It's really moody. It's raining throughout the entire episode, which is really cool." Director Frank Paur praised Spectrum's animation. "We wanted to keep the show heavy on the mist, the rain. I wanted reflections, mist, gentle rain to play up the whole motif. I was really worried at first that it would go to a bad studio."
Story editor Michael Reaves' script was edited by Martin Pasko. Paur redid the last act himself. "The original ending had a fight in the sewer between Batman and Killer Croc," said Paur. "Killer Croc escapes to a Seaworld park where he gets knocked into a pool of electric eels."
