Hayden Panettiere and the cast of ‘Heroes’

Hayden Panettiere (front left, in cheerleader outfit) joins the season one cast of the TV series Heroes. The cast is, in roughly back-to-front and left-to-right order: Sendhil Ramamurthy, Tawny Cypress, Greg Grunberg, Leonard Roberts, Santiago Cabrera, James Kyson Lee, Masi Oka, Milo Ventimiglia, Adrian Pasdar, Hayden Panettiere, Ali Larter, and Noah Gray-Cabey. This is a 2007 promotional photo from NBC. The supernatural drama ran for four seasons, from 2006-10. Hayden Panettiere played Claire Bennet, a high school cheerleader with the superpower of rapid cellular regeneration. Hayden Panettiere was born in 1989, so she turned age 18 the year this photo was taken -- surprisingly age-appropriate, given Hollywood's tendency to cast 20-somethings as teenagers.
