Hayden Panettiere recently talked to UK's Titan Magazine about what her fellow Heroes costars are like. Here's what she had to say:

"Adrian Pasdar, we've always said, is like the big brother. He always wants to take you here, take you there – he's the leader when [cast-members are on tour together]. Greg Grunberg is a goofball, Milo Ventimiglia is more of a flirt, Sendhil Ramamurthy and Masi Oka are great.

Ali Larter and I are girls, we stick together. Jack Coleman I'm very close to. I get to work with him a lot, and he's so much fun. He's so funny and he's such a bright man. It's fun to be around somebody like that who is bright, but funny at the same time. Zach Quinto, who plays Sylar, is funny as anything, and he's a good friend, too.

And Ashley Crow, who plays my mom – they all have their own personalities, and it's a hoot when we get together.

"Everyone has a crush on either Milo or Sendhil, but then I look at Greg and Adrian and Masi, and I see that everyone has crushes on them, too. We have a cast full of heartthrobs, what can I say? It's not only a large cast, but it's a large cast of really good actors. When you're around such good actors, you want to bring yourself up to their level and strive to do your best.

At the same time, in this show, we don't always get the chance to work with each other, so it's almost like showing off every time you get to work with [any cast-mate]. You're so excited, because it's like, ‘Ooh, I've got to be really good, because I'm working with so-and-so today.'"
