The coin-op boxing game played in the film is "K.O. Fighters" made by the National Novelty Company of Minneapolis, Minnesota c. 1926-28. New, it cost $225 ($3,175 in 2017). In perfect, restored condition, at auction in 2017, this machine could fetch $6,000-10,000.

The white football seen in the warm-ups for the night game at the end of the film was used in the NFL for such games from 1929 to 1955. It was considered to be more visible to the players and fans than the typical brown football. By 1956 better stadium lighting, especially needed for television, made the white football obsolete.

Making his film debut is Elroy "Crazylegs" Hirsch, then a first year member of "The Los Angels Rams (portraying a "Backfield" member of "The Chiefs"). He is "called out" by "The Chiefs" Coach Lenahan as "Hirsch". Elroy would later star in his film Bio, "Crazylegs" (1953) and the prison saga, "Unchained" (1955), the film which introduced the classic, "Unchained Melody". But perhaps his best-known film role was as the co-pilot in "Zero Hour!", the character spoofed by Kareem Abdul-Jabbar in its parody "Airplane!"

Jacques Tourneur never saw a football game prior to working on this movie.

Bill, the old player who winds up being dropped from the team, tells Pete he has "19 hundred dollars" (one thousand, nine hundred dollars) after playing all those years, which is now the equivalent of twenty thousand dollars.

Argus says that Wilson played three years in college and three years "up here", meaning professional football. That would make WIlson in his mid twenties. Victor Mature was thirty-six when this picture was released.

Kenny Washington, who plays Benny, played college football at UCLA on the same team with Jackie Robinson and future actor Woody Strode. He and Strode were two of the first black players in the NFL; Washington played for the L.A. Rams from 1946 - 48. He had been out of football for a year when he appeared in this picture; he makes a one handed, over-the-shoulder catch during practice without a scene cut or a stunt double.
