Pamela Burkhart – That ’70s Show

On the nostalgic hit comedy That ’70s Show, Jackie’s mother appears in the first season and then disappeared all the way until season six, Pam Burkhart, Jackie’s mom, was originally portrayed by Eve Plumb. After the long hiatus, Brooke Shields stepped in to become the new Pam.

Pam always had a strained relationship with her daughter Jackie for various reasons, so the change of casting made some sense. Shields stuck around for one episode in the seventh season as well, but her character didn’t make the cut in the eighth and final season.
