'Avengers: Endgame' Cast Answer Stephen Colbert's Most Burning Questions

If you could learn anything from Marvel Studios' "Avengers: Endgame," what would it be?

They said it couldn't be done, but Stephen Colbert assembled a superteam of "The Late Show" staffers to ask stars of "Avengers: Endgame," Chris Evans, Scarlett Johansson, Chris Hemsworth, Don Cheadle, Mark Ruffalo, Brie Larson, and Jeremy Renner their most burning questions.

Here are several factoids we learned during "Just One Question: Avengers: Endgame Edition":

1. The true villain of "Avengers: Endgame" is not Thanos, but "chafing," according to Chris Evans (Captain America). “If you’ve ever run through an inter-dimensional portal wearing a skin-tight bodysuit, you know what I mean," said Evans.

2. As for Captain Marvel's secret weapon for taking down the Mad Titan? "It's compassion," quipped Brie Larson, before immediately responding with, "No, I'm going to punch him into the sun."

3. The key to assembling furniture is not Mjolnir, but Flinjor, Thor's trusty allen wrench, according to Chris Hemsworth. "It's forged by Dwarven blacksmiths, available on Nidavellir, or IKEA," revealed Hemsworth.

4. What's the hardest part of playing the Hulk? "It'd definitely have to be the workouts where I have to put on about 1200 pounds of muscle," exclaimed trained method actor Mark Ruffalo.
