 Over the course of moving from studio to studio, the script was heavily rewritten.Many felt the final screenplay mirrored the life of legendary Roller Derby star, Ann Calvello, who in 1953, divorced her husband, left her young daughter with her ex-husband's family while she returned to the skating world to make a living, something which was unheard of during the 1950s.The screenplay perfectly embodied Calvello's real life struggles.
