Eva, who is dating Ryan, is tipped to play a mysterious figure called Cat in the movie.
Rob Zabrecky portrays a cab driver in the film, which will by Ryan's directorial debut and begin shooting in Detroit in May.
Ryan has said that having a strong cast will help to improve his confidence as a first-time director.
"I feel that as the cast grows, the more confident I am because I know how much you can depend on your actors if you have great ones," he said.
Matt is best known for being the eleventh incarnation of the Time Lord on the BBC series, although he has had roles in films such as Bert And Dickie, Clone and the upcoming Horrid Henry 2: The Movie.
