Another American is set to invade Downton Abbey.
In a surprising/exciting bit of casting news, TV Line confirms that Oscar nominee Paul Giamatti has been cast on the British sensation as Harold Levinson, the maverick, brother of Elizabeth McGovern's Cora.
Giamatti is best known for big screen roles such as Sideways and Cinderella Man, but earned an Emmy Award and a Golden Globe for his portrayal of the title character in HBO’s miniseries John Adams.
He also stopped by for a memorable guest-starring stint on 30 Rock in 2010.
Downton Abbey, meanwhile, returns to PBS on January 5.
