Stuart Fails To Save The Universe: Green Lantern Out, The Flash Steps In
Deadline reports that the Stuart Fails To Save The Universe creators wanted Green Lantern for a DC crossover but the Lanterns series blocked it, so the team pivoted to The Flash to navigate the multiverse; the episode features Mr. Freeze in Gotham, with the crew chasing a Golden Age Flash to help, and the writers (led by Zak Penn and Bill Prady) use meta-humor to poke fun at DC lore. The show has been renewed for a second season.
