Retroactive Recognition: Jessica Alba as a rival to Alex for one of her crushes. Also Larissa Oleynik, who was really popular in the late 90's and early 2000's and still has somewhat of a career.
What Could Have Been: The original idea was for the show to be called "High Voltage" and to star a boy with special powers. However, when the series was pitched to Nickelodeon, it was decided that the main character should be a girl. And, thus, the idea was retooled into The Secret World Of Alex Mack.
