Avengers: Endgame, with its 3 hours, 2 minutes runtime, is expected to break its predecessor's record as the longest Marvel film, which clocked in 149 minutes. The news about the film's length was broken by theatre websites AMC and Fandango. "3 hours, 2 minutes. #AvengersEndgame," tweeted Fandango on Monday.

Marvel head Kevin Fiege had hinted at the runtime in an interview to Collider earlier this month, without divulging the specifics. "We're gonna release the movie at the exact right running time. I'm telling you this, it's gonna be perfect. It's gonna be the exact running time that the movie needs to be."
