Dan Landsman (Black) is serious about his Pennsylvania high school's 20th reunion and considers himself chairman of its organizing committee. Dan lies to his wife and his boss about a fake business prospect in Los Angeles so he can talk to Lawless in person. To Dan, he's a superstar, a cool kid from high school. "The D Train" rides entirely on its excellent cast. Even beyond his celebrated performance in 2011's "Bernie," he's achingly real and wrenchingly vulnerable here, giving heart to a character so unlikeable that even his eventual self-awareness wouldn't be redemption enough. The film ventures into brave territory for a buddy comedy with its twist on the trope of drunken one-night stands, but it ends up disappointingly sticking with stereotypes. The D Train," an IFC Films release, is rated R by the Motion Picture Association of America for "strong sexual material, nudity, language and drug use.
