Peter Dinklage joins cast of George R.R. Martin's Game of Thrones

Tom McCarthy has come aboard to direct HBO's fantasy pilot Game of Thrones, for which the star of his first feature, The Station Agent's Peter Dinklage, has been tapped for a key role, according to The Hollywood Reporter.

Based on George R.R. Martin's best-selling Song of Ice and Fire novels, Thrones is described as an epic struggle for power set in a vast and violent fantasy kingdom. Dinklage will play Tyrion, the queen's brother, who is treated as an outsider because of his size.

Thrones marks the first TV directorial gig for McCarthy, an actor who wrote and directed two features, 2003's Station Agent and 2007's The Visitor, both of which landed him Indie Spirit Awards.
