"There's a party scene at the end of the movie. And the director's like, 'Evan, kiss Emma'. It wasn't scripted and I got really awkward and really weird and forgot what to do, and then I kissed her. It was good, but it was super awkward and so I felt weird about it. So I was like, 'That was like kissing Cloris Leach'," he added.
