It may not quite be the "Mad Men" cast's situation, but "Game of Thrones" stars have a lot of secrets they have to keep as well. Of course, the hit HBO show is based on George R.R. Martin's "A Song of Ice and Fire" book series, but because "Game of Thrones" still tells its own story, mums the word when it comes to spoilers.
But "Game of Thrones" star Alfie Allen, who plays Theon Greyjoy on the series, can't seem to zip his lips tight enough. The actor -- who's also pop star Lily Allen's brother and the subject of one of her songs -- told Rolling Stone that he's basically a "human spoiler," which has its consequences.
"I'm really bad at keeping secrets ... There was a press thing going on after the premiere in L.A., and I wasn't allowed to go on that," Allen told Rolling Stone. "It's quite annoying having to keep tight-lipped about it. Then again, playing the game is quite fun."
Season 2 ended ambiguously for Theon (a burlap bag was placed over his head as he lay unconscious), but Allen didn't think twice about telling people he was alive (though not so much well) in Season 3. "I would speak to people and they'd say, 'What are you up to?' and I'd say 'I've just been shooting the third season of "Game of Thrones,"' and they'd be like, 'What?'" he told the magazine. "It's really annoying, because I ruined it for people."
Allen does want "Game of Thrones" fans to enjoy watching sans spoilers, even if he can't help but spill the beans. In June 2012 after the Season 2 finale, he told TV Guide, "You've got to be a little bit on your guard ... You just don't want to ruin things for people out there ... I feel quite sorry for the people who haven't even gotten into Season 1, who read articles about it in the newspaper or in the magazines, and it so blatantly talks about Ned Stark's death. It's ruined it for them straightaway before they start watching it. It would be great if you could just leave it to surprise, but it's only so long you can hold back on spoilers."
