Heroes' Milo urges fans to 'expect the unexpected'

Heroes star Milo Ventimiglia has told fans to 'expect the unexpected' for the new season of the hit US drama series.

Milo, who plays Peter Petrelli in the show, dropped hints about how his character develops in the upcoming third series.

Speaking at the launch party in Los Angeles, the actor told OK! Magazine's US edition: "Peter is not quite himself. He really is influenced by the people around him and may be acting out of character."

Other Heroes stars on the red carpet included Hayden Panettiere, Jack Coleman, Ali Larter, Masi Oka, Zachary Quinto, and Adrian Pasdar.

Meanwhile, Jack Coleman, who plays Hayden's TV dad Noah Bennet in the show praised his on-screen daughter for the way she handles life in the media spotlight.

"Her poise is extraordinary," Noah said. "I couldn't handle her life as well as she does. There's no way I could handle people saying the things about me that they say about her."

The new third series of Heroes will hit US screens on September 22.
