Snoop Dogg is a big Soulja Boy fan. In fact, the 39-year-old rapper believes in him so much that he's pumping him up in a clip from an upcoming documentary about the Atlanta, Ga. star.

In the snippet from 'Soulja Boy: The Movie,' Snoop Dogg is shown talking about Soulja Boy's career, comparing his own experiences with that of the 21-year-old rapper. "A lot of people don't understand that this young man's struggle is my struggle," Snoop says. "When he went and make his records and made his name and did what he had to do, that's the same struggle that I went through."

According to the description, the movie takes an "unprecedented and illuminating look at the life and career of one of the most controversial and successful music star sensations of the digital era." The film was directed by Peter Spirer, the man behind 'Rhyme and Punishment,' 'Notorious B.I.G. Bigger than Life" and 'Tupac Shakur: Thug Angel.'

In addition to interviews with his family and other artists, the documentary also offers live footage of Soulja Boy performing 'Crank That,' 'Turn My Swag On,' 'Kiss Me Thru The Phone,' 'Donk' and more. Fans can get a copy of the film when it arrives on Oct. 18.
