Catalog log

Broadcast listing — not a TV Flash recap.

Still the gold standard for Western superhero animation.

The first useful thing *Batman: The Animated Series* does is treat Saturday morning like prestige genre. A noir-styled Batman stalks an art-deco Gotham where villains are tragic theatrical forces. Bruce Timm and Eric Radomski built a timeless design language — black sky, sharp shadows, jazz menace — for a 1992 Fox Kids premiere. Kevin Conroy's Batman and Mark Hamill's Joker became definitive voice performances for a generation. Arleen Sorkin's Harley Quinn spun out of this series into comics and films. Kids' TV…
