I asked the distributor, Sony, which version was correct, and the answer was, essentially, both. The studio calls it “a creative decision” with the ellipsis placement depending on the context. That’s about all it will say other than confirming that for review purposes, the ellipsis goes before “in.”

[Read A.O. Scott’s “Once Upon a Time … in Hollywood” review.]

If it were up to us, we’d eliminate the ellipsis altogether. The title reminds a lot of film fans of the Sergio Leone productions “Once Upon a Time in the West” and “Once Upon a Time in America.” And that’s fitting because in Tarantino’s movie, DiCaprio’s character, an actor named Rick Dalton, is wooed to star in spaghetti westerns as a way to revive his career.

But notice what’s missing from the Italian movies? That’s right. There’s no ellipsis.
