Game of Thrones star Lena Headey has promised that the second season will be "even more crazy".The actress told the
MTV Movie Blog that the HBO drama's cast and crew have been inspired by the success of season one.
"I can tell you that season two is even... more exciting," she said. "We've all been liberated because people really love the show, so we've really gone for it."
Headey added that her character Cersei has a "crazy relationship" with her brother and new second-in-command Tyrion (Peter Dinklage).
"There's a big arc with Cersei and Tyrion," she hinted. "They bring out each others' crazy."
Of her Thrones role, Headey added: "It's intriguing because she's crazy. Under the whole stoic thing, she's a little nuts."
The star previously claimed that new episodes of Game of Thrones will see Cersei "losing control" of her newly-crowned son King Joffrey (Jack Gleeson).
The second season of Game of Thrones will premiere in early 2012 on HBO in the US and on Sky Atlantic in the UK.
