Topher Grace, who played the lead role in That '70s Show, left the show towards the end of its run, and the show suffered as a result. However, he looks back at his time on the show fondly and is grateful for the opportunities it gave him. He left the show to pursue other acting opportunities, including playing Venom in Spider-Man. Behind the scenes, Topher wasn't known for partying like the rest of the cast and preferred to do his own thing. Despite his departure, Topher remains close to his former co-stars and would be open to a reunion of That '70s Show in the future.
