In an interview with Zap2It, star Hayden Panettiere said she had “no idea of any intention”. She further clarified, “It would be fun to do, but I know nothing about it.” This isn’t like the Arrested Development movie. God only knows if that one will get off the ground, but whenever it comes up, whoever is asked always talks about how a script is being written and they’re trying to all organize a date. They say those things because they actually want that movie to happen. Something tells me most of the people involved here couldn’t care less, at least now that they have other shit going on.
Don’t hold your breath on this project ever coming around. Even if those involved are desperate for work, ordinarily, people tend to make films about projects that were popular over the long haul, or at least ones that slowly gained a cult following over time. Heroes never recovered after the first episode of the second season, and if anyone ever revisits the project, it will likely be a full scale reboot with new actors. Your best chance to see this cheerleader is in the upcoming Scream 4.
