Fans who were won over by Kristen Bell's breakout role as feisty, teen detective-in-training "Veronica Mars" (UPN, 2004-07) might have been surprised to know that the young actress' roots were in musical theater. Bell had already appeared on Broadway twice when she was cast in the lead of the critically acclaimed television series that generated a small, but loyal following over its three years on the air. She went on to prove even more versatility in a campy Showtime adaptation of "Reefer Madness: The Musical" (2005) and another regular primetime role playing an unusually gifted but mentally unstable woman on the sci-fi phenomenon, "Heroes" (NBC, 2006-2010). While Bell's fledgling film career included brief dips into horror and little-seen indie comedy, a leading role in "Forgetting Sarah Marshall" (2008) launched her romantic comedy career and bumped up her status to big league Hollywood films. From there, she starred in a variety of films like "You Again" (2010) and "Burlesque" (2010), before returning to the small screen with a leading role on "House of Lies" (Showtime, 2012-16). As she graced the tabloid pages with her high-profile marriage to actor Dax Shepard, Bell caused an Internet sensation when she and "Veronica Mars" creator Rob Thomas raised $2 million through online donation site Kickstarter to make a big screen movie of their signature show. After becoming a superstar for the toddler set with her lead role in the animated smash "Frozen" (2015), she returned to her newfound role as a comic heroine with starring turns in Melissa McCarthy's "The Boss" (2016), animated hit "Zootopia" (2016) and R-rated comedy "Bad Moms" (2016). With her self-possessed demeanor, quick wit and dark edge, Bell remained one of the more uniquely talent stars working in both a film and television.
