Though she wore hairpieces in the film, producers had Lynda Carter dye the very front of her hair bright fire-hydrant red. This caused for awkward moments when she was off the set as the rest of her hair was still a dark brown color.
For this television movie, former "Wonder Woman" actress Lynda Carter wore one of the first brown colored contact lenses made. They were difficult to wear though as the lenses were made of glass.
Carter had to learn several tap and Spanish style dances for the role.
In real life Rita Hayworth was forced to alter her appearance because she was told she looked too ethnic (due to her Spanish heritage). Prior to this she was only offered roles that were stereotypical. After a year of procedures she had the look the studios wanted and she started to get more roles. Rita Hayworth was of Spanish descent and Lynda Carter is of Mexican descent.
