Robert Pattinson is amassing quite the list of leading ladies.
Deadline reports that Sarah Gadon has signed on to star alongside Pattinson in the big screen adaptation of Don DeLillo's book "Cosmopolis," . Gadon will play Pattinson's character, Eric Packer's, estranged wife.
Gadon joins director David Cronenberg's star-studded cast, which includes also Paul Giamatti. "Cosmopolis" features the story of a young, shallow Wall Street hotshot stuck in a dangerous limousine ride through New York City. A thriller set mostly in Packer's limo, the action sees him fighting for his life as an assassin and a series of disasters conspire to take him out -- all while he bets his entire personal fortune on the Yen.
Gadon is perhaps best known for her role in the ABC show "Happy Town."
Pattinson has a busy 2011; he stars opposite Reese Witherspoon in their upcoming film, "Water For Elephants," a period circus drama set to hit theaters in April, and is filming "Breaking Dawn," the final chapter of "Twilight."
The star's most prominent leading lady is, of course, Kristen Stewart in their epic "Twilight" series. Off-screen, they've long been rumored to be a couple, and the British star recently opened up, at least slightly, about their relationship in an interview with Italy's Style Magazine:
"My private life is off-limit. I've never spoken about my flirts, I'm not a man for short and superficial love affairs," Pattinson said (via translation from English to Italian to English). "I don't talk about my relationships with female friends, not to mention how I don't talk about my relationship with Kristen Stewart, an actress I admire because she's a real person, and a real actress. It was the chemistry I had with her helped me to get my role in Twilight."
