Sylvester Stallone and Dolph Lundgren Had a Rocky Reunion at Boxing Documentary Premiere

While they have a lot of fun together now, and are even collaborating on new action drama series The International, Stallone recently admitted that he wasn't Lundgren's biggest fan when they first met . "He was like the real Terminator," Sly said, recalling the moment that Lundgren was cast to play Drago. "And I go, I hate this friggen' guy. I hate him! He's just too good lookingtoo perfect. And if I loathe him, I'm sure the world will."

A version of the rivalry that Stallone and Lundgren depicted on-screen also plays out in One Night, which Stallone co-produced through his company Balboa Productions.

The documentary is about real-life boxing giants Anthony Joshua and Andy Ruiz Jr. , and follows the epic showdown between the two fighters earlier this year which saw Ruiz knock Joshua out for the first time in his professional career, seizing his WBA, WBO, and IBF titles in the process.

"He just decided, you know what? I'm going to rewrite this fing book," Stallone says of the history-making moment in the film. "That's when the pure savagery kicks in... Andy smells blood and he smells defeat... It just wasn't supposed to happen, but it did."
