Who would have ever thought the former heavyweight champion of the world, Mike Tyson, would make his big comeback outside of the ring?  This Friday, Iron Mike's critically acclaimed documentary, “Tyson,” is in theaters.  On Wednesday, the stars of Hollywood and sports came out to support one of the most controversial and talented boxing figures of all time. 

The New York City premiere was packed with celebrities like Hollywood legend Christopher Walken, boxing icon Joe Frazier, Oscar nominee Rosie Perez and media mogul LA Reid. R&B singer Mario, who just released his new single, "Break Up," raved about Iron Mike.

"Untouchable, never happening again ever in life—he was a phenomenal boxer.  I think the things that he went through made him as good as he was. He was hungry."

Anthony Anderson, who has a recurring role on “Law & Order,” said, "I don't think legacies can be defined, it's something that we witness.  It's epic in portions, the rise and fall of a man and a boxer—to see him rise again.  I'm just here to learn something new that I don't know about him and I hear that is what this film does." 

Nick Cannon, who just recently celebrated his one-year wedding anniversary with Mariah Carey, said Mike inspired him.

"His vigor, consistently just going hard all the time, from beginning to end.  The things that he came from and the man that he made himself to be is incredible."  

Hip hop definitely represented for Mike at the premiere.  Legendary hip-hop pioneer Ice-T said, "Mike is just raw, real.  I was fortunate enough to meet Mike when he was 21.  He was excited to meet me.  He was like, 'Oh sh*t, Ice-T.' It was love.  His whole get down was so gangster.  Just go up in the ring and beat m*therf*ckers down!  You had to love it."

Nas, who is arguably the Tyson of hip hop and was a producer on the film, talked about Mike's impact, "We never had anybody represent us on the level that Mike Tyson represented.  He's a leader."  He also stressed the importance of Mike telling his story. "To get out there and give people his life, it takes a brave and intelligent man. He's really brilliant.  There is a lot to learn from him."

However, no one says it better than Mike.  Surrounded by his children, the Brooklyn icon explained his impact on hip hop and pop culture.

"Everybody comes at a particular time.  Jack Johnson was fighting during ragtime and at the top of jazz.  Jack Dempsey did the roaring ’20s.  Joe Louis did the Depression.  Everybody is in a particular time and in that particular time they shine in certain circumstances."  Mike also said he is working on his autobiography with Jamie Foxx, but was still basking in the glow of the critical success of his film.

"I didn’t think it was going to come to this degree.  I didn’t think it was going to be this serious."

"Tyson" open in select cities this Friday.
