Oprah Buys Chaz Bono Doc

Before the movie debuts at the Sundance Film Festival later this month, Oprah Winfrey's cable upstart OWN has snapped up the rights to Becoming Chaz, a documentary that follows Chaz Bono's gender reassignment journey.

Deadline reports that OWN is planning a major party at the festival and will announce the acquisition there.

The film is directed by Fenton Bailey and Randy Barbato, the duo behind The Eyes of Tammy Faye, Inside Deep Throat, and Party Monster.
