Addison Timlin and her magnificent 19-year-old breasts have officially signed on to star in director Stephen Sommers big screen adaptation of horror author Dean Koontz’s bestselling novel “Odd Thomas.” The gorgeous Philadelphia-born actress will play Stormy Llewellyn, girlfriend to protagonist Odd Thomas (Anton Yelchin).

Odd Thomas tells the story of a short-order cook who can speak with the dead and identify evil forces. When a mysterious man arrives in his small California town, Thomas is convinced that doom accompanies the stranger.

Timlin, best known for her topless performances as actress Sasha Bingham on Showtime’s “Californication,” replaces British newcomer Lily Collins in the film and reportedly beat out actresses Emma Roberts (Scream 4), Kat Dennings (Thor), and Portia Doubleday (Youth in Revolt) for the role.

Odd Thomas is budgeted at under $30 million and will go into production this summer in New Mexico.
