Thesp to play the older sister to a budding male stripper

Cody Horn has landed one of the female leads in Steven Soderbergh’s male stripper pic “Magic Mike,” joining Channing Tatum, Alex Pettyfer, Matthew McConaugey and Matt Bomer.

Pic follows a young male stripper (Pettyfer) learning the ropes from a veteran (Tatum), and draws upon Tatum’s previous life in the trade.

Horn will play Paige, the older sister to Pettyfer’s character.

Nick Wechsler and Gregory Jacobs are producing with Tatum and his 33andOut Prods. partner Reid Carolin, who’s also scripting the project.

After initially casting Pettyfer and Tatum as leads, Soderbergh took his time with the remaining cast while Carolin touched up the script. In recent weeks, the cast has filled out with “True Blood”‘s Joe Manganiello and Riley Keough also joining the cast.

Horn, whose casting was first reported Monday by IndieWIRE blog The Playlist, is the daughter of former Warner Bros. prexy Alan Horn. She’s currently shooting “End of Watch” starring Jake Gyllenhaal and Michael Pena.

She is repped by Paradigm and Untitled.
