According to Batman: The Animated Series, young Bruce Wayne grew up watching the pulp adventures of the Gray Ghost (voiced by none other than Adam West) on television. And the first half of this Gray Ghost fan film feels like a dream the adult Batman might have after falling asleep watching old episodes.
The Gray Ghost: The Lost Reel was directed by J.L. Topkis, written by Matt Landsman, and inspired by the Batman: The Animated Series episode "Beware the Gray Ghost." The peek into an imagined Gray Ghost episode is neat (with actor Forrest Lancaster doing the Adam West voice as the Gray Ghost/Simon Trent), but the beginning feels like Batman's own fantasy, hitting home how he became the hero who wasn't there when he was a child.
