That '70s Show is an American television period sitcom that centers on the lives of a group of teenage friends living in the fictional suburban town of Point Place, Wisconsin, from May 17, 1976, to December 31, 1979. It debuted on the Fox television network, first airing on August 23, 1998, running for eight consecutive seasons, and concluding with the 200th episode on May 18, 2006.

The main teenage cast members were Topher Grace, Mila Kunis, Ashton Kutcher, Danny Masterson, Laura Prepon, and Wilmer Valderrama.

Mila Kunis

Mila Kunis as Jackie Burkhart: The youngest member of the group, Jackie starts the series as the pretty, rich, spoiled, selfish, conceited, and annoying immature girl. She likes to give thoughtless and superficial advice, which occasionally turns out to be correct. As the series progresses, she strays from her self-centered ways and becomes sweeter. Partly as a result of these changes, she and Donna become better friends. By the end of the series, Jackie has dated most of the males in the group: Kelso, Hyde, and Fez.

Note worthy: She was nominated for a Golden Globe Award for Best Supporting Actress and a Screen Actors Guild Award for Outstanding Performance by a Female Actor in a Supporting Role in Black Swan

Topher Grace

Topher Grace as Eric Forman (seasons 1-7; guest star, season 8): Eric is a nice guy, generally geeky, physically slight, and somewhat clumsy. He is a smart-aleck with a fast wit and a deadpan sense of humor. He convinces his parents to let his best friend Hyde move in with them, making Hyde like a brother. His father, Red, is always hard on him. Eric is in a relationship with his longtime love and neighbor Donna Pinciotti. He decides to become a teacher after high school, and he leaves the series at the end of the seventh season to teach in Africa. Although mentioned in every episode, he does not appear during the final season until the end of the series finale.

Note worthy: He appeared on Spider-Man 3 as Eddie Brock/Venom.

Ashton Kutcher

Ashton Kutcher as Michael Kelso (seasons 1-7; recurring, season 8): The dim-witted pretty boy of the group who wants to coast through life on his good looks. He spends the first half of the series in a relationship with the equally vapid Jackie. His best friend is Fez. He fathers a baby girl named Betsy during the seventh season. He attempts to become a police officer but gets kicked out of the police academy because he does just about everything wrong. He gets a job as a security guard at a Playboy Club in Chicago, and he leaves the series during the eighth and final season. He only appears in five episodes during season eight, including the series finale.

Note worthy: Kutcher would replace Charlie Sheen in the hit CBS sitcom Two and a Half Men.
