It seems that we might be going on quite a ride with an NBC hit series next season... a carnival ride. MTV Movies Blog recently spoke with Heroes star Hayden Panettiere about the upcoming fourth season of the show.

"The next season of Heroes has a lot of characters that are coming in," says Panettierre, "There's something called The Carnival... which is kind of the opposite of what The Company was. There's a lot of new, cool characters."

There have been a spate of new actors signed on to the show, including Prison Break's Robert Knepper, who has recently signed on to portray the villian Samuel. According to Next On Heroes, it seems that Samuel is a carnival barker, and Ray Park is in talks to portray the mysterious knife-throwing carnival character.
