Believable as a hero or a cad, this handsome actor should have gotten his big break as one of the buddies in the testosterone-driven indie Swingers, but he was upstaged by his costars, including a young Vince Vaughn. Ultimately his career took off when he embodied an unmotivated employee in the 1999 anticorporate comedy Office Space. Although the film wasn't initially a hit, it became a cult favorite around the time Livingston began popping up on the small screen, including recurring parts as a zealous prosecutor on The Practice and a commitment-phobic novelist on Sex and the City, and his Golden Globe-nominated turn as a real-life paratrooper in the lauded WWII miniseries Band of Brothers. Livingston continues to expand his repertoire, from supporting parts in impressive indie features (Adaptation, The Cooler) and feature films (The Time Travelers Wife) to starring roles on the small screen, including a plum assignment as an FBI hostage negotiator in 2006's Standoff and as chief engineer in the 2009 space thriller Defying Gravity.
