Did You Know?


The title of this episode may have come from a line in Cormac McCarthy's ultra-violent old-west epic Blood Meridian Or The Evening Redness In The West (1985). On page 148 in the Vintage International edition (1992), the line reads: "A lobe-shaped moon rose over the black shapes of the mountains dimming out the eastern stars and along the nearby ridge the white blooms of flowering yuccas moved in the wind and in the night bats came from some nether part of the world to stand on leather wings like dark satanic hummingbirds and feed at the mouths of these flowers."

Classic Batman: TAS
21 December 2016 | by (United States) – See all my reviews

'On Leather Wings' wasn't the premiere episode, but it sure does lay down the fundamentals. Batman as a detective, working the case3 with crime scene analysis and actual legwork; even as he works in opposition to an array of trigger happy cops (while Gordon stands aside as a conscientious objector).

This is an exciting episode, with Batman taking on both the police department and a giant bat. The animation works nicely in the action scenes, particularly the big aerial chase scene. A solid treatment of both the Dark Knight and the misguided mad scientist.
