Editing Any Given Sunday (section)

===Development===
Oliver Stone developed a script called ''Monday Night'' written by [[Jamie Williams (American football)|Jamie Williams]], a former [[tight end]] for the [[Nebraska Cornhuskers]] and later the [[San Francisco 49ers]], and Richard Weiner, a [[sports journalist]]. Stone separately acquired the [[spec script]] ''On Any Given Sunday'' by [[John Logan (writer)|John Logan]]. Stone later amalgamated a third screenplay, ''Playing Hurt'' by [[Daniel Pyne]], into the project.

As of May 1, 1999, the screenplay's cover page listed the following writers: original draft by Jamie Williams and Richard Weiner, John Logan, Daniel Pyne; subsequent revisions by [[Gary Ross]]; revisions by Raynold Gideon and [[Bruce A. Evans]]; revisions by John Logan; revisions by Lisa Amsterdam and [[Robert Huizenga]]; latest revisions by Oliver Stone.

The [[Writers Guild of America]] ultimately awarded screenplay credit to Logan and Stone, with "story" credit to Pyne and Logan. Williams and Weiner went uncredited for their original screenplay, but were credited for their work on the film as technical consultants.

The screenplay was also based in part on the 1994 book ''You're Okay, It's Just a Bruise: A Doctor's Sideline Secrets'' by Robert Huizenga. Huizenga was the intern doctor for the [[History of the Los Angeles Raiders|Los Angeles Raiders]] in their 1980s heyday, working under Dr. Robert T. Rosenfeld, who dismissed many players' injuries with the phrase, "You're okay, it's just a bruise".

James Woods's character is based on Rosenfeld. His first diagnosis of "Cap" Rooney's career-threatening injury at the beginning of the film is "you're okay, it's just a bruise". Huizenga left the Raiders in the early 1990s, disgusted at the way that the medical advice was kept from players and Rosenfeld being allowed to continue treating them after several mishaps, one of which is closely mirrored in the film—Shark's neck injury and risk of sudden death, based on the real-life [[Mike Harden]] case.
