IMAX sequences would remain largely intact -- full widescreen with the rest of the movie letterboxed --on Blu-ray, director Christopher Nolan pushed for Academy members to receive that version as a screener (why not give them a guided tour via BD-Live?), prompting Warner to mail them ahead of time offering the option of Blu-ray or DVD. The Hollywood Reporter mentions other studios are thinking about making the switch -- notably Sony regarding Will smith's upcoming Seven Pounds -- but haven't done anything yet, with concerns about cost and piracy. We wouldn't be surprised to see watermarking systems like the one Fox recently adopted come into widespread use, as much as studios want to avoid leaks they still want their productions seen in the absolute highest quality, right? Still, the first hurdle is making sure people can actually watch them, the report ends mentioning several members tossed the letter since they don't own a Blu-ray player yet.
