Topher Grace as Eric Forman
Topher Grace played the earnest, awkward Eric Forman for the first seven seasons. His character served as the moral and emotional center of many storylines. Grace departed at the end of Season 7 to pursue other opportunities but made a brief return in the Season 8 finale. His portrayal balanced comedy with sincerity, contributing significantly to the show’s early identity.
Mila Kunis as Jackie Burkhart
Mila Kunis portrayed Jackie Burkhart across all eight seasons. Initially the aloof popular girl, Jackie evolved into a complex character with lasting friendships and romantic entanglements. Kunis’s consistent presence provided continuity, and her character’s growth mirrored the series’ shift from high-school antics to adult responsibilities.
Ashton Kutcher as Michael Kelso
Ashton Kutcher played the confident, charm-driven Michael Kelso in Seasons 1–7, with a return in the Season 8 finale. Kelso’s lighthearted antics and romantic misadventures made him a fan favorite. Though Kutcher left the regular lineup early in Season 8, his cameo in the finale helped close the book on the character’s arc.
Danny Masterson as Steven Hyde
Danny Masterson brought deadpan humor and countercultural edge as Steven Hyde. Central to the group’s dynamic but often outside social norms, Hyde offered a grounded, sarcastic foil to Eric. Masterson exited before Season 8 but appeared again in the finale, acknowledging the character’s unresolved storyline.
Laura Prepon as Donna Pinciotti
Laura Prepon’s Donna Pinciotti balanced toughness and vulnerability across all eight seasons. As one of the few long-running female leads, Donna’s evolution—from high-school girlfriend to self-assured adult—highlighted the show’s efforts to develop its women beyond stereotypes. Prepon appeared consistently through the series finale.
Wilmer Valderrama as Fez
Wilmer Valderrama’s Fez offered offbeat humor and an international flair. Though his character’s origins were ambiguous for years, Fez became a core member of the friend group. Valderrama remained through Season 8, contributing to both comedic and heartfelt moments that defined the ensemble’s chemistry.
Debra Jo Rupp as Kitty Forman
Debra Jo Rupp anchored the parental presence as Kitty Forman across all eight seasons. Her steady, empathetic performance provided stability for Eric and the group. Rupp’s consistency helped humanize the adult world of the show, making family dynamics a reliable source of both humor and comfort.
Tommy Chong as Leo Chingkwake
Tommy Chong portrayed Leo Chingkwake as a laid-back, occasionally unreliable friend. After a prominent run through Season 7, his appearances were reduced in Season 8. Chong’s recurring presence added a slice of counterculture realism, even as the show transitioned away from his more eccentric storylines.
Cast Changes and Continuity Across Seasons
