‘Thunderbolts*’ Director on That Credits Scene, Shame Rooms They Didn’t Use and Making a Marvel Movie About Depression: ‘I Don’t Want This to Be the Weird One’

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.
