 In the original script, the character of Rosalie (the woman in the  wheelchair that Peggy Sue encounters at her high school reunion),  was a gymnast in high school who was crippled in an accident. The  original script spent a lot of time showing Peggy Sue trying to take  advantage of her knowledge of the future: inventing pantyhose,  encouraging people to invest in Xerox, and trying to prevent Rosalie  from injuring herself.
