Parsons, who stars on TV's "The Big Bang Theory," would play the role of Elwood P. Dowd in Mary Chase's Pulitzer Prize-winning comedy for Roundabout Theatre Company. Roundabout declined to comment to The Times.
Chase's durable, amiable comedy follows the story of a man who befriends a 6-foot-3-inch rabbit that only he can see.
Harvey originally played on Broadway at the 48th Street Theatre, opening Nov. 1, 1944. The production — helmed by Tony Awards namesake Antoinette Perry — played 1,775 performances before closing Jan. 15, 1949. The play won the Pulitzer Prize and was adapted for the screen as a 1950 vehicle for James Stewart.
