"Thunderbolts*" director Jake Schreier talks about the post-credits scene, what Bucky and the Red Guardian's shame rooms would've been, and making a summer blockbuster about depression.

When did you shoot the end credit scene?

That was shot maybe four weeks ago, and I did not direct that. That’s the Russos on the set of “Avengers: Doomsday”. I got to be there, which was very fun, to watch your buddies go on to this grander scale.
