There's apparently a growing market these days for "dorky guy" movies. Movies like The Forty Year Old Virgin, Superbad, and last month's Forgetting Sarah Marshall take characters who might normally be laughed out of online dating services and turn them into big-screen heroes and romantic leading men. Guys who were once relegated to the roles of sidekicks, best buds, and jokes are taking the forefront of stories as the stars. One of the latest entries in this reborn genre is A Good Old Fashioned Orgy, about a thirty-year-old man who throws a sex party when he's forced to move out of his parents' vacation house. (Another article even describes the character as an "Apatowian manchild.") But it's not just the dorky guys having all the fun this time; The Hollywood Reporter reports that Lindsay Sloane has just joined the comedy cast.
