Two and a Half Men fans kept up with the sitcom over the years due to the chemistry between cast members Charlie Sheen, Jon Cryer, and Angus T. Jones (and, later, Ashton Kutcher). But another part of the show's charm came in the performances of many guest stars over its 12-season run, which fans continue to enjoy in reruns today.
Two and a Half Men: The Best Guest Stars
Of course, womanizer "Charlie Harper" dated dozens of women—many of them short-lived guest stars—during his seasons as a cast member. But "Alan," "Walden," and even "Evelyn" were in relationships with partners played by A-list guest stars.
At other times, popular celebs made cameo appearances on Two and a Half Men, drawing laughs for the randomness of their presence (like Gary Busey). Others, such as Michael Clarke Duncan, Jason Alexander, and even Arnold Schwarzenegger, filled general roles on the sitcom over the years. The cast's off-screen partners even made more than a few appearances on the show, too.
Two and a Half Men aired for 12 seasons and a total of 262 episodes before it concluded in 2015. Find out the show's very best guest stars in our gallery!
