In the movie Mission: Impossible - Fallout Ethan Hunt gets the mission details in Homer's Odyssey.
Why no other book?
Is there any significance to using that specific book?
Homer's Odyssey is the story of Homer's long struggle to return home after the Trojan war.
In Mission Impossible: Rogue Nation, Hunt is being hunted and he is far away from home. This is just a simple throwback to MI:5 by Christopher McQuarrie.
“At the beginning of the film, the book The Odyssey was chosen for a very specific reason. The journey my character, Ethan Hunt, and his team go through is an odyssey inspired by and reflective of that story. It’s an epic personal tale, and there are enormous emotional stakes for the characters.”
From the Featurette "Behind the Fallout", Tom Cruise has this to say:
The book The Odyssey was chosen for a very specific reason. The Journey that Ethan Hunt and his team go through, it is an Odyssey and definitely reflective of that story as an epic tale. It's a personal tale and there's incredibly huge stakes.
