Rachel McAdams in talks to join Bradley Cooper in rom-com

After Emma Stone, Rachel McAdams is the latest Hollywood beauty to join the untitled romantic film being directed Cameron Crowe.

The film, which is slated for a September start, will see McAdams play the ex-girlfriend of Bradley Cooper, the Hollywood Reporter said.

Scott Rudin is producing the movie which revolves around a defense contractor (Cooper) who is overseeing a weapons satellite launch from Hawaii teams up with (and falls for) an Air Force pilot (Stone) to scuttle the launch. Mystical island forces and a talking computer also play a part.

McAdams next stars in 'About Time'.
