OH HEY, THEY ARE. i'm glad she has some around, i didn't investigate her credits too much beyond making sure they weren't taken! looking at his filmography though i think she might've been a little intimidated by working with him around then post-blue valentine and all of that, she was having kind of a rough time professionally so she might've been a little more neurotic on set at first, so maybe to loosen up she proposed a night out where they could try and get into character a little? since the dialogue was improvised she would've wanted a good rapport between them so she wouldn't fuck things up
