Kristen Stewart and Elizabeth Banks have been cast in The Big Shoe.

The actresses join Jim Sturgess (Cloud Atlas, Across the Universe), who plays a talented shoe designer forced to break free from a family that wants to turn his designs into mass-produced knock-offs to make money.

The family hires psychotherapist Mary Kay (Banks) and "muse" Delphi (Stewart) to try to lure the designer back to work.

Steven Shainberg (Secretary) will direct the film, and he said of the project: "The Big Shoe gives me the opportunity to explore a playful, romantic, sexy, intimate connection just as Secretary did.

"Not since that film have I had a script that combines eroticism and humour in such a fun way. This is a script dear to my heart, and I intend to make a truly unique film from it."
