Eric Roberts joins Heroes

Eric Roberts is joining the cast of NBC's hit Heroes. Roberts will play an associate of mysterious H.R.G. (Horn-Rimmed Glasses).

Roberts starred in the ABC sitcom Less Than Perfect as news anchor Will Butler. He currently has a recurring role on Showtime's series The L Word.

H.R.G., played by Jack Coleman, is a mysterious agent seeking knowledge about the "heroes," regular people who have genetic alterations that give them superpowers. He is the adoptive father of Claire, a teen who has the ability to regenerate herself and is referred to only by his nickname.

Heroes is the highest-rated new show of the 2006-2007 season. The series defended its turf against Fox's hit 24 last night, with an episode that featured the addition of an "invisible man," played by former Doctor Who, Christopher Eccleston.
