(KGTV) — Christopher Nolan's ‘The Odyssey’ has been a big hit with moviegoers.

But would you believe the film has also turned the nearly 2,700-year-old epic poem into one of the most sought-after books in the world?

It's true.

According to the book industry sales tracker Circana BookScan, sales of The Odyssey are up 76% compared to last year in the U.S.

And it's spiking even more in other countries.

July sales of the book were up 600% in South Korea and more than 1,000% in parts of the UK.

Audio books are in high demand as well.

Spotify says audio book streams of The Odyssey have spiked more than 300%.

The movie isn't doing too shabby either, grossing more than $900 million globally.
