Uma Thurman and Luke Wilson will star in “Super Ex,” a romantic comedy Ivan Reitman will direct for Regency Enterprises. The script, by Don Payne (“The Simpsons”), has Thurman playing a superhero who falls for a regular guy. He’s OK with her superhuman abilities but can’t take her neediness. When he dumps her, she uses her powers to turn the guy’s life into a nightmare. “Super Ex” will shoot in New York this fall.
