Stephen King isn't a stranger to having his written work adapted for television viewers to enjoy, but he's still envious of George R.R. Martin's work on "Game of Thrones."

King, 66, explained to The Los Angeles Times that he doesn't get territorial when showrunners develop his novels for television or films. However, when he heard Martin penned some scripts for the HBO series, he couldn't help but get a little jealous.

"I knew that George R.R. Martin had written a few episodes of 'Game of Thrones,' and I was very jealous," King said.

The writer will help in the creative process when asked, but doesn't get upset with adaptations don't do particularly well at the box office or draw in viewers at home.

"It's a no-lose situation," King told the LA Times. "If it's good, I just say it was based on my work. If it's bad, I just say, 'Well, that wasn't my idea.'"

In an interview with BuzzFeed, King explained that he has had little control over adaptations once he sells the film rights to his work.

However, he is eager to see the TV adaptation of his hit novel "The Dark Tower," which has been stalled multiple times.

"I was very excited when Ron Howard got involved with that project," King said. "His original take on it was the best. He wanted to do the movies - three tentpole movies - interspersed with a number of TV series that covered Roland and his adventures as a young man. It was a brilliant concept, and I'm pretty sure it would have worked. [But] what sometimes happens in Hollywood and in filmmaking is, the financing fell apart, or the studio started to have second thoughts."
