"Into Thin Air" author Jon Krakauer doesn't seem to be pleased with the movie "Everest" that is currently screened in theatres worldwide.

"Everest" directed by Baltasar Kormakur is blasted as "total bull" by Krakauer, the author of the book 'Into Thin Air' which covers the story of eight people that were killed while climbing the peak in 1996. Though the events in the film are just the same as the book, the book was not attributed as the main source material. Rather, the film-makers and the writers opted for original screenplay based on the research they made themselves, according to Entertainment Weekly.

"It's total bull," Krakauer said about Everest. Anyone who goes to that movie and wants a fact-based account should read Into Thin Air." Krakauer is much displeased with his character played by Michael Kelly, portrayed like refusing to help with a rescue in the movie since he was snow blind then.

"I never had that conversation," the author of the book said. "Anatoli came to several tents, and not even sherpas could go out. I'm not saying I could have, or would have. What I'm saying is, no one came to my tent and asked," reported Hollywood Reporter.

Krakauer regreted his decision of selling the rights of the book. He said that dramatic movies take dramatic licences, the film makers feel they can do anything to a story when a document is signed.

Meanwhile the director said that "To be honest I wasn't that interested in telling a story about a writer on a mountain. I've seen a lot of movies about writers. His book is a first-person account and there are a lot of things that he assumes or thought that happened that didn't really happen. This is the story of a group of people who are going up this mountain and I wanted to be true to that."
