In the movie, Val Kilmer (as John Holmes) wears a chain around his neck that holds a ring. The ring is was the actual wedding band that John Holmes gave his wife, Sharon, when they got married in 1965. Sharon loaned it to Val to give him good luck on the movie. When the movie was over, Sharon then gave the ring to Dawn Schiller.
The movie did not portray that, while John was being beaten up at Nash's house, Liberace's lover, Scott Thorson, was present. It was his testimony that eventually led to the indictment of Eddie Nash by federal authorities.
In the real life story, John did not call Eddie Nash after the robbery at his place. Rather, John was spotted by some of Nash's associates in Hollywood. They noticed that John was wearing some of the jewelry that was stolen in the robbery and told Nash about it. John was then accosted by two gunmen who then took him to Nash for questioning.
During the production Val Kilmer became so immersed in the making of the film that he began a photography project which has blossomed into a behind-the-scenes pictorial book which he chose not to release.
Lions Gate was not sure how to market this film due to the significant drug content, intermittent porn reference and the brutal violence depicted. The content in question remained, but the film then was only given a limited theatrical release in the domestic market for awards consideration.
Both Val Kilmer and Kate Bosworth have played famous DC Comics character. Kilmer played Bruce Wayne/Batman in ''Batman Forever (1995)'' and Bosworth played Lois Lane, long-time partner of Batman's close friend and ally Clark Kent/Superman, in ''Superman Returns (2006)''.
