Mike Birbiglia says that his new movie about an improv group, Don’t Think Twice, uses plenty of real-life influences and anecdotes. Jimmy Fallon’s life isn’t among them, although Fallon shared a funny note about what happened when he himself got the call from Saturday Night Live — when Fallon called The Groundlings in Los Angeles to share the news with his former improv teacher, the comedy collective there informed Fallon first that he owed them money if he wished to continue his learning there.

Don’t Think Twice opens Friday.
