Ready to Rumble (2000) on Netflix

Gordie Boggs and Sean Dawkins are two dumb hardcore wrestling fans who worship WCW's World Champion, Jimmy King. When they attend an episode of WCW Nitro to see King defend the title from Diamond Dallas Page, they witness him losing in a dishonest effort and being fired by the president, Titus Sinclair. After their truck breaks down on their way home, the guys figure it must be a test to find King and avenge his unfair loss and firing. They find him and persuade him to go back to WCW and get the title back. King shows up on Nitro with Gordie and Sean, and King pins Page after all hell breaks loose. This causes Sinclair to strike up a deal: if King defeats Page at the next pay-per-view, he gets his title back plus $1 million; if he loses, he is never allowed back in WCW. So Gordie and Sean take King back to basics, and rebuild him to win the WCW World Heavyweight Championship once and for all.
