What scenes were shot in IMAX?
The escape from Jakku. I believe it started as Rey and Finn started running and ended when the Falcon left the planet.
If it had to be one way or the other, I’m actually kind of relieved they’re not including the shifting aspect ratio on the 2D blu-ray. The 2D theatrical release with the locked aspect ratio is the one I’ve seen three times and will see at least once more when I go with my parents this weekend, so even if I do make it to an IMAX screening eventually, I expect the 2D to remain the “true” version in my own memory. Still, in a perfect world it would be included as an option on the 2D disc.
I completely understand why people don’t like shifting aspect ratios. It can be distracting. But I personally prefer to see as much as I can, especially because Abrams’ intention was probably to get the most he could out of a very square frame.
