The actor was the star of Sir Ridley Scott's 2000 epic, which raked in more than $450 million (£300 million) at the global box office and won five Oscars.
But Crowe was left fuming when he discovered assistants working on the film were receiving paltry wages - and allegedly threatened producer Branko Lustig with violence unless the issue was resolved.
In Nicole LaPorte's book The Men Who Would Be King: An Almost Epic Tale of Moguls, Movies, and a Company called DreamWorks, Lustig alleges Crowe told him, "You motherf**ker. I will kill you with my bare hands."
And the threat left Lustig so shaken, he considered calling DreamWorks boss Steven Spielberg to resign from the project.
He adds, "(I said,) 'Steven. I'm leaving. Russell wants to kill me. I'm leaving.'"
Crowe's spokesperson says of the claims, "I've been told that (online retailer) Amazon already has the book discounted. Go figure."
LaPorte's book goes on sale next month (May10).
The British Academy of Film and Television Arts (BAFTA) recognized some of the year’s best films on Sunday. "Gladiator" was chosen best film, and "Crouching Tiger, Hidden Dragon" took away best foreign-language film honors. Each of these Oscar contenders received four BAFTA awards in total.
Producers Douglas Wick, David Franzoni and Branko Lustig accepted the best film award for "Gladiator," praising director Ridley Scott during their acceptance speech, who lost out on the best director prize to Ang Lee for "Tiger."
Besides best foreign film and best director, "Crouching Tiger" also won for music (Tan Dun) and costume design (Tim Yip). Of BAFTA and the United Kingdom, Lee said: "You've always been great to me. This is like a second home to me now."
“Gladiator” also won the Orange Audience Award for most popular film of 2000. Scott thanked DreamWorks and Universal for their courage in backing a $100 million film in a genre that hadn't been touched for 30 years. "It is especially good to win this on my home turf as I spend so much time in the United States," Scott said during his acceptance speech. "I am absolutely thrilled."
Besides the BAFTA honor for best film, "Gladiator" also picked up awards for cinematography (John Mathieson), production design (Arthur Max) and editing (Pietro Scalia).
British effort "Billy Elliot" won three awards, including best British film, best actor (Jamie Bell) and best supporting actress for Julie Walters.
Julia Roberts was named best actress for her performance in the title role of "Erin Brockovich." Presenter Hugh Grant, and co-star in "Notting Hill," picked up the award for the absentee actress.
Best original screenplay and best sound awards went to Cameron Crowe’s "Almost Famous." Crowe's wife, Nancy Wilson, accepted his award, saying that Crowe was unable to attend the event as a double ear infection prevented him from flying. "He meant this movie as a love letter from his heart to music," Wilson said.
Steven Soderbergh's "Traffic" also won two awards, for adapted screenplay (Stephen Gaghan) and supporting actor (Benicio Del Toro).
Veteran casting director Mary Selway was given the Michael Balcon Award for her outstanding contribution to cinema. Actor Albert Finney was presented with a British Film Academy Fellowship for lifetime achievement, receiving a standing ovation.
