Now a big-screen star in, Peter Dinklage's breakout role was undoubtedly that of Thrones fan favourite Tyrion Lannister. But in his pre-Imp days, Peter won plaudits for a stint on edgy cable drama Nip/Tuck and his performance in both the UK and US variants of black comedy . And who can forget his hilarious turn as Miles Finch – the hot-tempered children's author who tussles with Will Ferrell's Buddy in festive favourite Elf?
Game Of Thrones isn't the first time that Lena Headey has played a formidable matriarch. In 2008-2009's Terminator: The Sarah Connor Chronicles, she took on the formidable task of stepping into Linda Hamilton's shoes. Her acclaimed performance earned Lena a cult following long before Cersei was on the horizon. 1993's The Remains Of The Day – nominated for a total of eight Oscars – and 2007's visceral blockbuster 300 are among the star's notable big-screen credits.
