For a time in the 2000s, Ben Stiller dominated big-screen comedy. As a charter member of the "Frat Pack," along with people such as Owen Wilson, Vince Vaughn, and Will Ferrell, Stiller had an incredible string of blockbuster hits, including Zoolander, Starsky & Hutch, Dodgeball: A True Underdog Story, Meet the Parents, and the Night at the Museum franchise. In recent years, Stiller's stepped away from comedy, moving behind the camera to helm acclaimed limited series such as Escape at Dannemora & Severance. In this episode of WTF Happened to this Celebrity, we take a look at his career, from his early days on The Ben Stiller Show, through his breakout in There's Something About Mary and beyond.
