The Secret World of Alex Mack

Though the character of Alex Mack was initially conceived as a boy, Nickelodeon had the writers change the character to a girl.

Near the end of the series' run, Lynch presented star Larisa Oleynik with a package deal that included a fifth season of the show and a feature film, but Oleynik turned the deal down.

Lynch, who had created the programs Night Tracks and Kids Incorporated, said the idea for the series was based on an incident from his own childhood.

What would happen to me?" For the fictional chemical GC-161 in the show, Lynch said he came up with the GC part of the name while doing DNA research, while the 161 came from the number eight.
