It's being reported that at least some of Rogue One will shoot on Arri's new 6k, 65mm-sized model of Alexa camera. But that's not all! These 65mm shots will use the 1.25x anamorphic Ultra Panavision lens recently revived by Quentin Tarantino and Robert Richardson for The Hateful Eight, which they shot on actual 65mm film.

Ultra Panavision (2.20:1 65mm film with a 1.25x squeeze) yields an extremely wide aspect ratio of 2.76:1. There were only a literal handful of films made in this format before it was abandoned, Ben-Hur probably being the most well-known example. Several years back I actually got to see an anamorphic 70mm print of the last Ultra Panavision film, Khartoum, which was released in 1966 and also happens to star Charlton Heston.

Gareth Edwards and his cinematographer Greig Fraser are clearly fans of the more old-fashioned formats, as they shot last year's Godzilla movie in panavision/cinemascope with 2x anamorphics using the alexa 4:3.

I wonder how much of Rogue One will shoot in this digital "equivalent" of Ultra Panavision and if the movie will shift to the ultra wide AR at certain points. Maybe they'll crop those shots to 2.40:1 while still taking advantage of the added resolution and detail?

Prequel fans: "How dare they film in more than 1080P."
