Charlie Sheen
Ashton Kutcher joined as Walden Schmidt. He did not take over the role of Charlie Harper.

Warner Bros. Television ended Sheen's contract in March 2011 after production interruptions and his public conflict with creator Chuck Lorre. The contemporary firing report describes an employment rupture, not a court determining a criminal allegation.
Sheen sued over the dismissal. The dispute was settled later that year, with the terms confidential.
The programme's solution was a new lead. Kutcher played Walden Schmidt, while Jon Cryer's Alan retained his identity and relationships. That changes more than the name over a familiar comic function. Alan is no longer responding to the brother whose home and habits organised the original arrangement. The continuing ensemble has to establish why this different man belongs in its day. 'Kutcher replaced Sheen' is accurate as a staffing summary and incomplete as an account of what the sitcom had to rebuild.
The later relationship also changed. Variety's account of Sheen's 2025 documentary notes his reconciliation with Lorre and appearance in Bookie. Losing this particular job did not mean the two men would never work together again. It did mean the sitcom had to reorganise its central arrangement while it was still running.
