James Corden enlists the cast of "Thor: Ragnarok" to crash a screening of the film and perform a live-action rendition starring Chris Hemsworth, Cate Blanchett, Tom Hiddleston, Tessa Thompson, Mark Ruffalo and Jeff Goldblum.
Cate Blanchett joins Ragnarok as the mysterious and powerful new villain Hela, along with Jeff Goldblum as the eccentric Grandmaster, Tessa Thompson as the classic hero Valkyrie, and Karl Urban will add his might to the fray as Skurge.
