Jenna Fischer is making her New York stage debut in Neil LaBute’s new play Reasons to Be Happy on the same day (May 16) as her TV show, The Office, airs its series finale. Fischer dropped by Late Night with Jimmy Fallon to discuss the serendipitous evening and her transition from L.A. TV star to New York stage star. Fischer also dishes about the casting process of The Office and just how John Krasinski ended up “her Jim”. A must-watch for any Office fan, check out the interview below, and don’t miss Fischer in MCC Theater's Reasons to Be Happy this spring at the Lucille Lortel Theatre.
