Entertainment Weekly gave us more informations about Legends of Tomorrow season 3 finale.
Something about Legends of Tomorrow? — Benjilau
How about this: “I think we achieve peak Legends in the last two episodes,” EP Marc Guggenheim says, teasing that the penultimate hour includes two of the crazier things the show has ever done with Barack Obama being attacked by Grodd and John Noble playing himself circa the shooting of Lord of the Rings. “Both moments are just so wonderfully joyous. They’re some of the best stuff we’ve ever done on Legends.” As for the finale, which he describes as “balls-out craziness,” expect many familiar faces to return — both in the hero and villain department. “It really feels like a real finale in that respect and we really draw together almost every thread and character that we’d established over the course of the third season, and yes, that includes Beebo,” Guggenheim says. “Beebo will make a phenomenal return that is quite awesome.”
