'Son of the Congo' Mesmerizes in Telling NBA Star's Inspiring Story

"Let's take a selfie," Oklahoma City Thunder forward Serge Ibaka tells his eight-year-old daughter Raine as they sit on a patio early in the film Son of the Congo . It's a sweet moment between the 25-year-old Ibaka and his young daughter — but also so much more, as the documentary that premiered at SXSW Interactive on Saturday night reveals to powerful effect. Son of the Congo, follows Ibaka on a trip home this past summer to tell his incredible story of escaping poverty and violence in Congo to become an NBA millionaire. The film is also notable for marking the first feature-length documentary produced by Grantland, the acclaimed ESPN-owned site founded by star columnist Bill Simmons in 2011. Ibaka said of the film, "I always said to myself since I was young that if I make it to the NBA, I want young people to know my story, to know where I come from."
