Sugar Ray Leonard has revealed that Hugh Jackman's biggest problem whist training for Real Steel was just letting go.
Sugar Ray was brought on board the movie to help with the boxing training of Jackman prior to the film.
Speaking to Collider Leonard said: "The biggest thing he struggled with was to let go and surrender, and drop his guard and be a fighter, and forget about Hugh and Broadway, and be the fighter and the trainer.
"That’s really difficult. With fight films and boxing films, the only ones that come to mind where the actor and actress let go and become that fighter were Raging Bull, Million Dollar Baby, Requiem for a Heavyweight, and The Fighter.
"They were people who had dropped their guards, and that’s very hard to do, for a superstar to let go of that thing. Once you do that, you know what it’s like to be a fighter, for a moment.
Real Steel is set in the future and sees boxing taken to a whole new level and robots have replaced humans in the ring.
Real Steel is released 14th October
