Becoming Chaz, the documentary about the former Chastity Bono that Deadline first reported was picked up by OWN in January ahead of its bow at the Sundance Film Festival, has gotten its TV premiere date: May 10 at 8 p.m. ET/PT. It will be the first movie under the OWN Documentary Film Club brand. Rosie O’Donnell will host a one-hour special afterward that will include an interview with Bono, whose gender reassignment journey is followed in the doc, which was directed by Randy Barbato and Fenton Bailey of World of Wonder.
