Robert Downey Jr., Chris Evans and Chris Hemsworth go in for the kisses in Avengers: Age of Ultron gag reel

There's a whole lot of kissing going on in the second Avengers: Age of Ultron gag reel…but the pashers aren't who we'd necessarily expect them to be.

Check them out in the video above. No wonder Scarlett Johansson is asking "What the f---?"!

Hey, it's great to see that superheros like Iron Man, Captain America and Thor are completely comfortable expressing their bro love. Can we get in on some of the action?
