Producer eyes movie on Mexican singer Gloria Trevi

An independent film company is developing a movie about Gloria Trevi, the fallen pop singer dubbed “Mexico’s Madonna.”
Swiss-born Christian Keller will make his directorial debut on “Trevi,” which is to be produced by New York-based Braven Films. Company head Frida Torresblanco, who once ran Alfonso Cuaron’s production company, will produce with Oscar-winning “Lord of the Rings” producer Barrie Osborne.
