Smith played Red Forman in the series, reprising his role from the original series That 70's Show, alongside Debra Jo Rupp, who played his wife Kitty in both series.
“I’ve loved every minute of getting to bring Grandpa Red to life for you all,” Smith continued. “I’ve said it before, but it’s worth mentioning again…this show had so much heart behind it and the most wonderful cast, writers, directors, producers and crew an actor could hope to work with. Thanks for letting Red and Kitty, their grandkid, all their grandkids friends and neighbors, the original cast members of That 70’s Show and all of our wonderful guest cast members entertain you for two seasons.”
That '90s Show was set fifteen years after the first, with the daughter (Callie Haverda) of Eric (original lead Topher Grace) and Donna (original lead actress Laura Prepon) visiting her grandparents (the Formans) for the summer.
Other original guest stars who appeared in the '90s edition included Wilmer Valderrama, Mila Kunis and Ashton Kutcher. The cast also included Ashley Aufderheide, Mace Coronel, Maxwell Acee Donovan, Reyn Doi and Sam Morelos.
However, in his post, Smith indicated that he doesn't think the series is completely dead yet.
“To steal Red Forman’s words…we aren’t going to be dumbasses…we will shop the show, because good grandparents would try hard to get these kids graduated from high school,” he ended his post.
