Heroes: meet season four’s new villain

Casting is underway for the fourth season of NBC's Heroes, with once more the pressure on to produce something better than the underwhelming season that proceeded it. It's fair to say that many are viewing the fourth season as a final throw on the dice, albeit one with some promise, courtesy of the return of Bryan Fuller to the writing team.

The producers have made a smart signing, however, by recruiting Robert Knepper to the cast. Knepper is best known as the thoroughly horrible Theodore ‘T-Bag- Bagwell in Prison Break, and he's going to be playing Samuel in the next Heroes season. Samuel, predictably, is not a very nice man, who's going to impact on several of the characters.

The new season starts shooting in the next few days, and will be on our screens in the Autumn.
