Most of the "Heroes" cast members had established acting careers prior to joining the cast. Some of them were series regulars on other hit television shows, while others were getting their feet wet when it came to notoriety. Debuting in 2006, "Heroes" ran four seasons before eventually getting canned for low ratings. Despite the show having a short run, it pushed all of these cast member’s careers forward in a positive manner.
As a "Heroes" cast member she started off as the adorable barely legal teenager, and by the end of the series she turned into a blonde bombshell. Since portraying cheerleader Claire on "Heroes," Panettiere has made it onto at least one sexiest female list since 2007. Her parents got the acting bug for Panettiere early on when they let her star in commercials at 11 months old. One of her most successful top billed movie roles was in the movie "I Love You, Beth Cooper!." She goes back and forth between acting in television shows, movies, and doing voice over work for both video games and animated features.
This Japanese-American actor could easily be crowned everyone's favorite "Heroes" cast member. Critics were also a fan of Oka's ability to portray the time traveler Hiro, and in 2007 he was nominated for Golden Globe and Emmy Awards. Not only does he act, but also works at Industrial Light & Magic creating special effects for the movies such as, "Pirates of the Caribbean: Dead Man's Chest," and "War of the Worlds." He gained those skills from Brown University where he graduated from with a degree in mathematics and computer science. Don't worry; he has not traded in his acting career for one in special effects, because in 2011 he starred in, "Friends with Benefits," and "Searching for Sonny."
Prior to becoming a "Heroes" cast member he was known for being every teenage girls favorite bad boy Jess on "Gilmore Girls." For ten straight years he was billed as the main character on one or more television series starting in 2001 with "Gilmore Girls." After his run on "Gilmore Girls" ended he starred in the television series "American Dreams," and "The Bedford Diaries." Both wound up cancelled, and in 2006 he landed the part of Peter Petrelli on "Heroes." In 2011 Ventimiglia is taking his movie star good looks back to the big screen by starring in, "The Divide," and "Criminal Empire for Dummy's."
Prior to being a "Heroes" cast member he already established a television career by playing CTU analyst Adam Kaufman during season 3 of "24." In 2006 his career took an unfortunate and somewhat desperate turn when he starred alongside fame-seeking diva Tori Spelling on her VH1 series "So NoTORIous." Maybe he left that off his acting resume, because later that year he was cast in "Heroes" as the creepy mysterious villain named Sylar. He started acting in 2000, but his first major movie role did not come until 2009 when he starred as Spock in "Star Wars." He seems to be making up for lost time because in 2011 he can be seen in the movies, "Margin Call," "Girl Walks Into a Bar," and "What's Your Number?”
