Rogue One will continue the Star Wars tradition of pushing the technical nature of film making forward by filming some of the feature in 6K resolution.
The Hollywood Reporter broke the news that parts of Rogue One will be filmed with the Alexa 65 6K camera:
Parts of Star Wars: Rogue One and Mission: Impossible – Rogue Nation were shot with Arri’s Alexa 65, a large format, 6K resolution model of Arri’s popular Alexa camera that is available exclusively through Arri Rental.
Likely this means there will be IMAX sequences in Rogue One, as they specifically call this a large format model of the 6K camera.
Star Wars is meant to push the boundaries of film making. George Lucas intended to shoot all three Prequels digitally, but was only able to do the last two as Sony hadn’t finished developing the digital cameras at the time he made The Phantom Menace. Some fans were upset to learn that JJ Abrams ignored this aspect of making a Star Wars film when he went with 35mm film in The Force Awakens, so it’s nice to see future Star Wars movies will move things forward once again.
