Listen to Marvel’s Avengers Sing Christmas Carols

Here is a viral mashup that is sure to get Comic Con fans into the holiday spirit. Video editor James Covenant edited together movie clips from the Marvel Cinematic Universe franchise to make it look like “Joy to the World” was being sung by the Avengers cast and “Jingle Bells” was being sung by Groot, the giant, tree-like extraterrestrial being from Guardians of the Galaxy.

Around this time last year, he edited footage from Star Trek to make it look like Captain Jean-Luc Picard (Patrick Stewart) was singing “Let It Snow.”
