Career: Sheen's screen debut came in 1974's The Execution of Private Slovik. Despite dreaming of a baseball career, he began acting professionally in the mid-1980s. He appeared in Red Dawn, Lucas and Ferris Bueller's Day Off before Platoon made him a star in 1986. He followed it up with Wall Street, Young Guns, Eight Men Out, Major League and two Hot Shots! movies. Sheen's career suffered as a result of his drug abuse during the 1990s, but he returned to form with appearances in Being John Malkovich, Spin City, Two and a Half Men and Anger Management.

Career: Cryer's first TV role came in 1984's No Small Affair. Only two years later he became something of a cult icon thanks to Pretty in Pink, in which he played Phil 'Duckie' Dale, before landing smaller parts in Superman IV: The Quest for Peace, The Outer Limits, Becker and Two Guys, a Girl and a Pizza Place, among others. He began work on Two and a Half Men in 2003, playing single parent Alan Harper, who moves in with his brother, portrayed by his Hot Shots! co-star Charlie Sheen.

Career: Jones landed his first film role with a bit part in Simpatico, but he got his big break starring alongside David Arquette in See Spot Run. This led to him being cast as the cute but surly Jake in Two and a Half Men in 2003 alongside co-stars Charlie Sheen and Jon Cryer. He has also starred in TV movie The Christmas Blessing and had a guest role on Hannah Montana Forever.

Career: Richards moved to Los Angeles where she gained more modelling work, but she soon learnt that, at five feet six inches, she wasn't tall enough. She began attending acting classes and made her TV debut in an episode of Life Goes On in 1990. Her first film was 1991's Loaded Weapon 1, which was followed by numerous forgettable projects. Starship Troopers made her a star in 1997. Since then she's appeared in Wild Things, Drop Dead Gorgeous, The World Is Not Enough, Scary Movie 3, and Love Actually. She posed nude for a Playboy pictorial in 2004, and semi-nude - for charity - in another magazine shoot in 2006. Richards made two seasons of reality show Denise Richards: It's Complicated, starting in 2008. She failed to find her feet on the 2009 run of Dancing with the Stars, becoming the second contestant to be eliminated. She played the recurring role of Debra in American comedy drama Blue Mountain State, which ran during 2010 and into 2011.
