While the sequel doesnt yet have a firm release date, development is moving right along on Deadpool 2, and director Tim Miller and the films producers are now looking towards casting a key female role. Sources close to the production exclusively tell Collider that testing has begun for the character of Domino, and the actresses under consideration include Lizzy Caplan (Masters of Sex), Mary Elizabeth Winstead (10 Cloverfield Lane), Sienna Miller (American Sniper), Sofia Boutella (Star Trek Beyond), Stephanie Sigman (Spectre), and Sylvia Hoeks (Overspel).There could be other actresses included in the mix, but sources tell us that at least these six performers have tested or are going to test for the role.
Like Deadpool, Domino is a mercenary and a mutant, and her powers include the ability to initiate random telekinetic acts that turn probability in her favor. Additionally, she has a close connection to the mutant Cable, as her comics history found her becoming a partner, confidante, and lover of the mutant and frequent frenemy of Deadpool. It was previously confirmed during the post-credits sequence for Deadpool that Cable will appear in Deadpool 2, so the inclusion of Domino in the sequel as well makes sense.
