Peter Petrelli, Nathan's brother
Milo Ventimiglia stars in NBC's new ensemble drama series "Heroes" as Peter Petrelli, a male nurse and politician's younger brother who is plagued by nightmares that he can fly. Ventimiglia recently starred in Tom Fontana's series "The Bedford Diaries," which focused on a group of college students in a human sexuality class. He quickly garnered attention when he joined the casts of two critically-acclaimed television dramas: "Gilmore Girls" as the quiet and complicated Jess and NBC's "American Dreams" as a 1960s war radical. He was also a recurring character on David E. Kelley's drama "Boston Public." Before joining "Gilmore Girls," audiences became familiar with Ventimiglia when he starred in the Fox series "Opposite Sex," which secured him a holding deal with Warner Bros. His other television credits include guest-starring roles on primetime series such as "The Fresh Prince of Bel Air," "C.S.I.," "Sabrina the Teenage Witch" and "Promiseland." Segueing effortlessly between the big and small screen, Ventimiglia's passion for the art of acting keeps him drawn to both studio and independent features. He recently completed work on the sixth installment of the "Rocky" series, playing Sylvester Stallone's son in "Rocky Balboa." His other film credits include the Disney film "Stay Alive," the Wes Craven/Kevin Williamson thriller "Cursed," the indie film "Dirty Deeds," "Sheer Bliss" and "Massholes." Additionally, he starred in the short films "Nice Guys Finish Last" and "Must Be the Music," which debuted at the 1996 Sundance Film Festival to rave reviews. He currently resides in Los Angeles and enjoys skateboarding, snowboarding and wakeboarding. He also has a passion for restoring vintage muscle cars. His birthday is July 8.

Ok, I remember him in Cursed now. Good movie btw, I recommend it if you haven't seen it yet. He played the wresting jock.

There's a link to a forum at the Heroes website and on there people are speculating that Peter's power is being able to copy the powers of other heroes he's been in contact with. He doesn't get as strong powers as the person he copies from so it's more like he can mimic their abilities. His brother is able to fly so he can levitate. He's been in contact with the artist so he was able to draw stick figures of his levitation scene with his brother later on but not with the artistic ability that Isaac had. It's an interesting theory if true.

Have you noticed that Peter talks out of the side of his mouth a lot? It's hard to explain but it's like his face doesn't meet symetrically at his mouth. I had a lion hand puppet when I was little that's mouth wasn't stitched right so you had to adjust your hand at a slight angle instead of opening it straight up and down to make it appear to talk straight and Peter's mouth reminds me of that puppet. lol
