Who Played in That ’70s Show: A Complete Cast Guide

Overview

That ’70s Show is a long-running American sitcom set in the 1970s that centers on a tight-knit group of friends in suburban Wisconsin. This cast guide covers the core ensemble and many recurring characters, with brief career notes to anchor who played whom. The show uses a multi-cast structure, so multiple actors share the spotlight across its eight-season run.

Core Friend Group

The main circle of friends drives the series and appears throughout almost every episode. These actors portray high-school-age teenagers navigating life, romance, and family in the 1970s. Below are the primary six friends, their on-screen roles, and the actors who brought them to life.

Eric Forman

Topher Grace played Eric Forman, the earnest, somewhat nerdy point-of-view character and the son of Red and Kitty Forman. Grace’s performance anchors the show’s earlier seasons and establishes the group’s dynamic.

Michael Kelso

Ashton Kutcher portrayed Michael Kelso, the charming but dim-witted ladies’ man of the group. Kutcher’s comedic timing helped define Kelso as the loose cannon whose misadventures fuel many subplots.

Steven Hyde

Danny Masterson is Steven Hyde, the sarcastic, counterculture outsider with a dry wit and guarded demeanor. Masterson’s portrayal emphasizes Hyde’s loyalty beneath his abrasive exterior.

Donna Pinciotti

Laura Prepon plays Donna Pinciotti, Eric’s intelligent and independent girlfriend who often serves as the group’s moral compass. Prepon’s performance balances toughness and vulnerability.

Fez

Wilmer Valderrama plays Fez, a foreign exchange student with a distinctive accent and optimistic, kindhearted personality. Valderrama’s Fez provides much of the show’s warmth and comic relief.

Jackie Burkhart

Mila Kunis plays Jackie Burkhart, the wealthy, self-centered cheerleader who shifts from antagonist to friend over time. Kunis’s evolution mirrors the show’s move from episodic gags to more serialized storytelling.

Family and Authority Figures

Parents, police officers, and other adults shape the friends’ world. These roles are played by character actors who add stability and contrast to the teens’ antics.

The Forman Parents

Kurtwood Smith plays Red Forman, Eric’s no-nonsense, military-style father, while Debra Jo Rupp is Kitty Forman, the doting, sarcastic mother. Their contrasting styles create a grounded parental presence.

Leah and Bob Pinciotti

Tanya Roberts and Don Stark play Donna’s mother and father, Leah and Bob Pinciotti. Their marriage provides both comic relief and a backdrop of working-class realism.

Police and Other Authority Figures

Sheriff Harry Hyde, played by Tommy Chong, represents a laid-back, occasionally stoned authority. Local law enforcement and other adults appear intermittently, reflecting the era’s attitudes toward youth and responsibility.

Notable Recurring and Supporting Cast

The series features a deep bench of recurring characters, from love interests to high-school staff. These roles expand the world beyond the core friend group and introduce new dynamics each season.

Casey Kelso and Other Family Roles

Kylie and Asher Robbins portray Casey, Michael’s younger sister, across multiple seasons. Other relatives and guest characters appear sporadically, adding texture to the show’s small-town setting.

Teachers and School Staff

Coach Jackie Burmeister and others fill out the school environment, interacting with the main group during key episodes. These roles often serve as catalysts for milestone moments, such as graduation or prom.

Love Interests and Seasonal Arrivals

The series introduces several romantic interests and friends-of-friends over time, portrayed by various actors. These roles test the core group’s bonds and reflect evolving 1970s social dynamics.
