Synopsis (from July Vanity Fair): From Rich Moore, the Emmy-winning Simpsons director, the 3-D animated comedy stars John C. Reilly as the titular video-game villain, who grows tired of being the bad guy. After stopping by a support-group session for arcade villains…, he escapes his own video game and travels to others in hopes of proving that he’s an upstanding citizen. Along the way, Wreck-It Ralph meets Silverman’s Vanellope von Schweetz, a precocious ponytailed Sugar Rush character who makes light of Ralph’s woes.
