Over his fifty-year career he has received numerous accolades including a Golden Globe Award as well as nominations for four Primetime Emmy Awards.

Charlie Sheen followed in the footsteps of his father Martin Sheen in becoming an actor. He starred in a slew of successful films such as Red Dawn (1984), Platoon (1986), Wall Street (1987), Eight Men Out (1988), Young Guns (1988), The Rookie (1990), The Three Musketeers (1993), and The Arrival (1996). In the 2000s, when Sheen replaced Michael J. Fox as the star of ABC's Spin City, his portrayal of Charlie Crawford earned him a Golden Globe Award for Best Actor. He then starred as Charlie Harper on the CBS sitcom Two and a Half Men (2003–11), for which he received multiple Golden Globe and Primetime Emmy nominations, and as Dr. Charles "Charlie" Goodson on the FX series Anger Management (2012–14). In 2010, Sheen was the highest-paid actor on television, earning US$1.8 million per episode of Two and a Half Men.

Sheen was terminated from his Two and a Half Men contract by CBS and Warner Bros. following a public series of substance-abuse issues, marital problems and comments made towards the series' creator, Chuck Lorre. In 2015, Sheen publicly revealed that he is HIV positive which led to an increase in HIV prevention and testing which was dubbed the "Charlie Sheen effect".
