Prison Break star Robert Knepper is to join the cast of US TV drama Heroes as a new villain, according to industry newspaper The Hollywood Reporter.
The actor, who played the sinister Theodore "T-Bag" Bagwell on the prison drama which ended this year, will star in at least six episodes.
He is reported to play Samuel, a charismatic yet wicked man with a twisted sense of humour.
Nineteen new episodes are expected when
Heroes returns in the autumn.
NBC bosses also confirmed that Californication star Madeline Zima will be joining Heroes as a friend to current character Claire, whom she meets at college.
On the big screen, Knepper recently starred in Transporter 3 and The Day the Earth Stood Still.
He will next be seen in
Prison Break: The Final Break, a made-for-DVD follow-up movie to the series.
