Mike Birbiglia is a comedian, writer and director who's making a big career out of small films and comedy performances.

His latest film, "Don't Think Twice," is about a fictional comedy troupe that has to come to terms with the fact that one of its members just got his big break.

Birbiglia has had chances to go big (in sitcoms and such) but he says he likes what he's doing.

He also owes a lot to Nathan Lane, who threw his support behind Birbiglia's one man show "Sleepwalk With Me."
