Two and a Half Men (season 9)

The ninth season of Two and a Half Men premiered on CBS on September 19, 2011, with Ashton Kutcher joining the cast as Walden Schmidt. This season is the first without the show's previous star Charlie Sheen, and features a rebooted plot, marking a major change in the series by focusing on Alan and Jake coping with life after the death of Charlie, with help from their new best friend and housemate, Walden, a dot-com billionaire who is in the process of being divorced by his wife. The trio bond and form a surrogate family unit. This was the last season to air on Mondays.

Production
Following Charlie Sheen's firing on March 7, 2011,[1][2] there was much speculation as to whether the show would be canceled for good, following the cancelation of the previous season. Chuck Lorre revealed that he'd considered ending the show, but thought that it would've been "such a heartbreaking way to end".[3] On May 13, 2011, it was announced that Ashton Kutcher would be taking over from Sheen, playing new character Walden Schmidt.[4][5] It was also announced that the writers would kill off Charlie Harper.[6] For a revamped show, the producers re-decorated the main set of the beach house, which was used up until the final season.[7][8][9] The theme tune was also revamped, with two new singers used in the opening sequence. The new variation of the theme was used only until the end of this season, before another variation was used for seasons 10 and 11, except for a production error in the third episode of season 10 in which season 9's variation of the theme is heard.[10][11] Ashton Kutcher assisted Chuck Lorre with the creation of Walden Schmidt and co-wrote the story of "Slowly and in a Circular Fashion", which develops his character.[12] The character of Charlie Harper, despite being killed off, was re-introduced late in the season as a ghost in a woman's body for a guest reprisal, played by Kathy Bates.[13][14] Chuck Lorre described the casting as a "gender bending role".[15]

CBS president Les Moonves was extremely pleased with the season, saying "This show could last with the current numbers it has for many, many years."[16]Jon Cryer believed that Kutcher had added a new energy to the show and revitalized it.[17]
