Christopher Nolan's first trailer for The Odyssey dropped this week, and it looks spectacular. Epic sea battles, mythological creatures, that signature Nolan visual grandeur applied to Homer's ancient poem. Also: everyone sounds like they're from California.

The decision to shoot the entire film with American accents has sparked exactly the debate you'd expect. The Hollywood Reporter calls it "definitely a choice," which is entertainment journalism for "this is going to be divisive."

And it will be. Historical epics have long wrestled with the accent question. Gladiator went full British, which gave it Shakespearean gravitas but also made Romans sound like they'd attended Eton. Troy mixed accents chaotically - Brad Pitt's Achilles sounded American, Eric Bana's Hector kept his Australian tones, and Peter O'Toole's Priam delivered classical British theater.

Nolan chose uniformity. His Odyssey will be entirely American-accented, from Matt Damon presumably playing Odysseus to whatever unfortunate actor has to voice the Cyclops.

There's logic here. Ancient Greeks didn't speak English at all, so any accent is equally "inauthentic." Choosing American removes the class baggage British accents carry - the unconscious association that British = serious, American = commercial. It also makes the story more immediately accessible to the global audience that will ultimately determine whether a $200 million Homer adaptation works financially.
