Jonathan Nolan has heaped praise on his brother Sir Christopher Nolan's film The Odyssey.

The 49-year-old screenwriter-and-movie producer - who has collaborated with his 55-year-old sibling in the past, such as on his Batman trilogy - hailed the 2026 action-fantasy flick as "spectacular".

Jonathan told Cinemablend.com: "I'm not working on The Odyssey. I have seen The Odyssey. It's tremendous. It's an incredible achievement …

"I was fascinated by the Iliad and The Odyssey when I was younger, and I had some fun conversations with Chris about where he's taking it. It's a spectacular film."

Pressed on whether he has seen the entirety of the upcoming Greek mythology blockbuster - which is slated for a July release - Jonathan added: "I'm not sure I'm supposed to say that, but, yes, it's tremendous."

The Odyssey - which is based on Homer's epic of the same name - follows the king of Ithaca Odysseus (Matt Damon) as he struggles to return home after the fall of Troy, confronting monsters, gods and the consequences of his own choices along the way.

Meanwhile, his wife Penelope (Anne Hathaway) and son Telemachus (Tom Holland) fight to protect their fractured kingdom as they await the man who may never return.

The Odyssey also stars Robert Pattinson, 39, Zendaya, 29, Jon Bernthal, 49, Charlize Theron, 50, and 38 year old Elliot Page.

And the movie caused great excitement in 29 year old Holland.

In September 2025, he told reporters: "The script is the best script I've ever read.

"Chris [Nolan] is a real collaborator. He knows what he wants ... but it is not an environment where you can't pitch ideas or build characters in certain ways."

In January, meanwhile, Mia Goth (Melantho) dubbed working on The Odyssey as "one of the greatest experiences of my life", and relished working with Christopher.

The 32-year-old actress added to The Hollywood Reporter: "It really was. It was profound.

"I've been such a fan of his work for years. And so to have that opportunity and to witness him and how he directs was incredible. I took a lot from that. The trust that he has in actors was enlightening."

Christopher - who used "over two million feet of film" across The Odyssey's 91-day shoot - wanted to adapt the Homer epic to fill in "gaps in cinematic culture".

In November 2025, he told Empire magazine: "There's a bit of everything in it. I mean, it truly contains all stories.

"As a filmmaker, you're looking for gaps in cinematic culture, things that haven't been done before.

"And what I saw is that all of this great mythological cinematic work that I had grown up with - Ray Harryhausen movies and other things - I'd never seen that done with the sort of weight and credibility that an A-budget and a big Hollywood, IMAX production could do."
