Hot Docs, North America's biggest documentary film festival, kicks off its 2011 run on April 28 in Toronto. Jam-packed with documentaries running through May 8, Moviefone Canada will be there from start to finish, offering up looks at some of the festival's noted films.

Chaz Bono is a man.

This wasn't always the case. Gender transition is examined emotionally, spiritually and physically in the stellar documentary 'Becoming Chaz,' which captures the final moments of Sonny and Cher's daughter -- before she becomes their son.

The film joins Chaz and girlfriend Jennifer well into the process. What once was a lesbian couple now find themselves realizing the complications that come with transitioning. Jennifer is an amazing supporter with a great sense of humor about a new regime of surgeries, testosterone injections and weight gain -– but what about living with a man?
