WOW.. is it just me or is there tension between the two of them ; Bill Hader seems like he hates her and Amy looks genuinely pissed like at 3:22 and 15:44 when he makes fun of her old standup LOL
I've seen some other interviews with the two of them together and I have to say there was a fair bit of awkwardness. Especially during the second half of the Trainwreck promo tour (there were a few times where they barely even looked at each other). I mean I don't mind seeing co-stars have a bit of banter during interviews but it did go over the line a bit into spitefulness. And when they weren't bantering, they just looked like they wanted to be somewhere else.
I doubt they've stayed in contact since but then again you can't expect everyone to be best friends with each other.
