Stephen King has said he was shocked to hear Under The Dome being compared to The Simpsons.
His 2009 novel has been adapted for TV with Steven Spielberg as executive producer.
The novel is set in a small New England town that is suddenly sealed off from the rest of the world by an enormous transparent dome.
Some viewers have pointed out comparisons to The Simpsons Movie, in which the fictional town of Springfield was ensconced in an invisible dome.
But the Carrie author said: "I was totally gobsmacked and blind-sided when people started to say, 'Oh The Simpsons already did this'.
"I figured to myself, 'I am so glad that I wrote my book beforehand, otherwise I would have been down'.
"I saw the previews of that movie and I can't remember seeing a dome. So probably people are like, 'Oh sure you didn't!'."
The crime writer said that he's not precious about how his original material is used.
"You get ulcers. Besides, I'm a go-along guy. When I was a kid my mother used to say, 'Stephen if you'd been a girl, you'd always be pregnant', and there's some truth to that."
:: Under The Dome starts on Channel 5 on Monday, August 19.
