With the movie being filmed in Australia, virtually all of the young men playing prospective Aggie football players were Australian. Therefore, all of the Texas accents - as convincing as they might've been - were indeed fake.
Gene Stallings, a Junction Boy who later went on to coach at Texas A&M, in the NFL with with the St. Louis (now Arizona) Cardinals and then at Alabama (including coaching the Crimson Tide to their first national championship since Paul "Bear" Bryant's retirement and death in 1993), disputed the way that both the "The Junction Boys" book and movie portrayed Bryant. In a September 2006 interview with Tuscaloosa Magazine, Stallings had this to say: "Junction, Texas, was tough, but I didn't like the way the book...and movie portrayed Coach Bryant. He wasn't brutal; he was tough. That's a big difference. He wanted to bring us together, away from distractions, unite the team."
The Texas A&M Aggies' 1-9 season in 1954 immediately after the camp was the only losing season in Paul "Bear" Bryant's 38 years as a head coach.
While the various players featured in the film are fictional, they are based on actual Junction Boys. For example, Claude Gearhart (Ryan Kwanten) is based on Dennis Goehring, a guard who became known as a player who Bryant could not run off the team.
ESPN Outside the Lines (2005) aired a companion special to the film, "The Real Junction Boys", hosted by Bob Ley and featuring real life Junction Boys Gene Stallings, Dennis Goehring, Billy Schroeder, Elwood Kettler and Henry Clark.
