Editing Two and a Half Men (section)

=== Main ===
* [[Charlie Sheen]] as [[Charlie Harper (Two and a Half Men)|Charlie Harper]] (seasons 1–8), a charismatic [[Hedonism|hedonistic]] [[bachelor]], jingle/children's songwriter, Alan's elder brother, Jake's uncle and Jenny's father. Despite his arrogant and rambunctious demeanor, he does possess a kind heart, though he very rarely shows it. He is written out of the series at the beginning of season nine, after being pushed in front of a train and killed [[offscreen]], due to Charlie Sheen being fired from the show. In the episode "Why We Gave Up Women", Charlie's ghost, portrayed by [[Kathy Bates]], visits Alan and is forced to spend eternity in [[hell]] as a woman with a pair of testicles. He has a daughter named Jenny, whose existence he never disclosed to his family. In season 11, she resurfaces as an adult, but has no idea he had died. The series finale [[retroactive continuity|abandons]] the idea that Charlie is deceased by revealing that Rose faked his death and held him prisoner in a pit for four years. Brainwashed into a violent [[Psychopathy|psychopath]], he escapes and portends his imminent arrival by sending threats to Alan, Evelyn and Walden, as well as generous checks to Jake, Berta, Jenny and his ex-girlfriends, but a helicopter drops a grand piano on him and kills him just before he enters the beach house.
* [[Jon Cryer]] as [[Alan Harper (Two and a Half Men)|Alan Harper]], Charlie's younger brother, a struggling [[chiropractor]], Jake's twice-divorced father, Walden's best friend and Jenny's uncle. Alan is intelligent, a graduate of [[Cal State Long Beach]] but continually stricken with bad luck due to poor choices and mistakes, which are due to a lifetime of suffering from Charlie's abuse and Evelyn's neglect, as well as favoring Charlie over him. Due to a lack in income (partly the result of Charlie's sabotaging Alan's divorce-settlement by jilting Alan's lawyer in the episode "No Sniffing, No Wowing"), Alan is forced to sponge off people throughout his life, but he genuinely cares about others despite this. His poverty ultimately led to the demise of his business. In the 12th and final season, Alan agrees to "marry" Walden for the latter to adopt a child and for months, the two pretend to be a gay couple. In the series' penultimate episode, Walden and Alan end the marriage as Walden had successfully adopted a six-year-old named Louis. Alan finally proposes to Lyndsey and agrees to marry her (as well as move out) in the final episodes. Cryer is the only cast member who appears in all 262 episodes of the series.
* [[Angus T. Jones]] as [[Jake Harper (Two and a Half Men)|Jake Harper]] (seasons 1–10; guest, season 12), the [[slacker]] son of Alan and Judith and older half-brother (or brother, if Alan's paternity claim is to be believed) of Milly and cousin of Jenny. In season one, episode 17 ("Ate the Hamburgers, Wearing the Hats"), his real name is revealed to actually be Jacob. As he grows older, he changes from a rather bright (but gullible), independent child into a dimwitted buffoon (who is nevertheless good at blackmailing Charlie and Alan). He eventually enlists in the U.S. Army working as a chef. At the end of season 10, he announces that he is going to Japan for a year. Despite his absence, he is mentioned often in seasons 11 and 12 and makes an uncredited cameo via archive footage in season 12, as well as returning briefly in person in the series finale.
* [[Ashton Kutcher]] as [[Walden Schmidt]] (seasons 9–12), Alan's best friend, roommate and ephemeral husband. A friendly, hopelessly romantic internet tycoon, he is a billionaire despite being somewhat immature and [[Naivety|naïve]] for most of his life. He purchases the Harper beach house after Charlie's death. During his time in the household, he grows into a responsible adult and forms close friendships with Jake, Herb, Berta, Judith, Evelyn and Jenny. He also serves as a surrogate uncle figure to Jake, in place of Charlie. In season 12, he and Alan adopt a six-year-old boy named Louis.<ref>{{cite news|url=https://tv.yahoo.com/news/tca--ashton-kutcher-to-play-broken-hearted-internet-billionaire-on--two-and-a-half-men-.html?nc|title=TCA: Ashton Kutcher to Play Broken-Hearted Internet Billionaire on 'Two and a Half Men'|publisher=[[Yahoo!

* [[Marin Hinkle]] as [[Judith Melnick|Judith Harper-Melnick]] (seasons 1–9; recurring, seasons 10–12), Alan's selfish, mean-spirited ex-wife and Jake and Milly's mother. She considers Charlie's lifestyle and attitude to be a bad example for Jake and also occasionally has issues with Alan's own parenting practices.
* [[Conchata Ferrell]] as [[Berta (Two and a Half Men)|Berta]] (seasons 2–12; recurring, season 1), the family's outspoken housekeeper and close family friend. She shows great animosity towards Alan and Jake, while she adores Charlie and later, Walden. During the Kutcher years, her role was increased on the show, appearing in more episodes. Season 11 was the first season where she appeared in every episode. The role was originally only intended for a two-episode arc in the first season, in which she would leave as a result of Alan and his son moving in.<ref name="avclub.com"/>
* [[Melanie Lynskey]] as [[Rose (Two and a Half Men)|Rose]] (seasons 1–2; recurring, seasons 3–12), the Harpers' strange neighbor and Charlie's [[Stalking|stalker]] and friend. Initially, Charlie hated Rose and wanted nothing to do with her, but eventually they became friends and he later fell in love with her. In the ninth-season premiere, Rose claimed that Charlie "slipped" in front of a [[Paris Métro]] train after she had caught him cheating on her. She was later seen taking Bridget Schmidt under her wing as an apprentice stalker, but this storyline was eventually aborted. After formally meeting Walden at the local tavern, Rose rushed into a relationship with him and caused her ferrets to attack Walden and Alan when Walden broke up with her. Naturally, she continues to stalk Walden, as well as the Harpers, despite Charlie's apparent death. In the finale, she is revealed to have kept Charlie imprisoned in a pit for four years.
