fantastic! on inside llewyn davis he thought landing that movie was a prank and he had no idea how he even got there. on the first day he would've told her his suspicions that all of this was a con job. in general he's very relaxed, joke-y but knows to shut up and get serious if need be. with llewyn he would've tried to see if she'd hang out with him one on one before filming just so they could establish a small bond with one another. with once upon a time i assume his role is small, but he'll be overjoyed to see her!
