Emma Stone also is in the cast of the Sony movie, which is eyeing a September start.

Rachel McAdams is in negotiations to join the growing cast of the untitled romantic comedy Cameron Crowe wrote and is directing.

Scott Rudin is producing the movie, which already has Bradley Cooper and Emma Stone on board to star and is eyeing a September start.

STORY: Rachel McAdams to Star in Working Title's 'About Time'

The premise sounds pretty loopy for a romantic comedy: 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 will play Cooper’s ex-girlfriend.

The actress next stars in About Time, a romantic time-travel comedy from one of the masters of the romantic-comedy genre, Richard Curtis (Love Actually). The movie opens Nov. 8.

She is repped by UTA and Magnolia Entertainment.
