Topher’s film career would eventually prove to be fruitful, but it took quite a few years for that to happen. Many of his co-stars also went on to have successful film and movie careers.
Mila Kunis (Family Guy, Black Swan, Forgetting Sarah Marshall) and Ashton Kutcher (Punk’d, investing in basically every successful product, Two and a Half Men) experienced far more success despite sticking it out a bit longer on That 70’s Show — Ashton only by 3 episodes, but still.
Wilmer Valderrama, who portrayed Fez on the show, is currently starring on NCIS while Laura Prepon just wrapped seven seasons of Orange Is the New Black. As for Danny Masterson, aka Hyde, he was fired from his show The Ranch after allegations of sexual assault surfaced in 2017.
