The Berkshire Theatre Festival opens its Main Stage season with Enter Laughing, by Joseph Stein. Adapted from the novel by Carl Reiner, this comedy is about a young man trying to extricate himself from overly protective parents and two too many girlfriends, while struggling to meet the challenge of an insufficient amount of time and a dearth of acting talent. If the equation doesn't total up, the consequences do add up to an evening of hilarity. David (the young Carl) wants to be an actor, a Casanova, a man of the world. His parents want him to be a married druggist. Set in Depression-era Bronx, this cutting-the-cord, coming-of-age, Tony-Award winning comedy is directed by Scott Schwartz. There is a Talk-Back performance on Monday, June 23.
