Dustin Milligan was excited to work with the whole cast of "The People We Hate at the Wedding." As Kristin Bell's love interest in the film, most of his scenes are with her, and he was looking forward to acting with someone he respected so much. But, going into filming, he also had some apprehension. 

"I was a huge fan (of Bell) beforehand," he told The List. "you're always a little nervous about what you're going to get once you're on set and [find out] who this person is actually going to be in real life." As a fan he was nervous he might be disappointed with their actual interactions. Fortunately, she "exceeded expectations in every way," Milligan said. "[Bell] is truly lovely, genuine, caring, and a wonderful scene partner."

Describing working with her, Milligan said, "she's such a professional and so on it and ready to play. [She's] very game for finding all these little moments in between lines." That attitude made it easy to work with her and to build up the romantic chemistry between their characters.
