Hereâs a clip from Mike Birbigliaâs visit to last nightâs Jimmy Kimmel Live, where he talks about his new film Donât Think Twice, upcoming tour for the film, and why people who arenât into improv can still relate to the story. âA lot of the themes of improv are similar to the themes of life,â he says. âWith improv itâs something that has never happened before and will never happen again. And itâs true when you make a movie or work on a project of any kind with people â college friends, high school friends â itâs just a moment in time.â
