The movie is set in the world of urban horseback riding.

Idris Elba will star in and produce the indie Ghetto Cowboy.

The film follows 15-year-old Cole, who is forced to live with his estranged father, Harp (Elba), in north Philadelphia where, despite the surrounding poverty and violence, he discovers the redemptive world of urban horseback riding.

The movie is based on the 2011 novel of the same name by Greg Neri. Dan Walser and Ricky Staub wrote the screenplay, with Staub set to make his directorial debut on the project.

Elba will produce under his Green Door Pictures banner, along with Jeff Waxman, Jen Madeloff, Sam Mercer, Tegan Jones and Dan Walser.
