• Kutcher will be reprising his "That '70s Show" role of Michael Kelso alongside his wife Mila Kunis in the new spinoff.

Ashton Kutcher said returning to the set of "That '70s Show" for the show's upcoming spinoff — "That '90s Show" — was "nostalgic" and "really odd."

"We shot it," Kutcher said of the spinoff, speaking to Entertainment Tonight on the red carpet for the premiere of his new film "Vengeance."

"It's funny and it's weird. It was super nostalgic and really odd," Kutcher, who will be reprising his role as Michael Kelso, said.

"Going back into the basement — just going back into the set was weird. And then being around everyone, it's just bizarre," Kutcher continued.

The new Netflix series will feature much of the original cast, including Kutcher's wife and co-star, Mila Kunis.

Wilmer Valderrama, Topher Grace, Laura Prepon, Debra Jo Rupp, Kurtwood Smith, and Tommy Chong will all be reprising their roles in "That '90s Show."

Kutcher added that filming the spinoff has been "insane" in the best way possible, according to Entertainment Tonight.

"The fact that that happened is insane," he said.

Kutcher told Variety that he and Kunis both felt returning for the spinoff was the right thing to do.

"Mila and I were contemplating it," Kutcher said. "We thought, 'Listen, we're only in the position that we're in because of that show, so let's just go back and do this.' We just went back and had fun for a week. It was so random and fun."

"That 90s Show" has no official release date yet. It will be exclusively streaming on Netflix when it does release.
