I read in the Oblivion article that @Mike Sowa looks at the trailer as a mini version of the movie. That's quite an interesting thought. I know colorists who like to hang the master shots on the wall to see how everything match. A more digital friendy way to do this is to create a timeline with the master shots and use a lightbox feature.
Great insight @Dylan R. Hopkin! I like to keep it clean, and I prefer not to use plugins unless I need to. I remember the first versions of Resolve and how slow the NR was. I haven't gotten into the feature since the original version because it gave such a bad impression. The feature was überslow and made the system crash every time.
It could be quite interesting if BMD could make grain that can compete with the real grain plates out there.
The devil is in the contrast, but you could be limited by poor dynamic range as you're not working on the original material. That said, I think you've done a great job! Congratulations, I'm looking forward to see your next project!
The first thing to consider when approaching a look like this is the exposure. With higher luma levels you will get access to a color palette that is closer to the orignal look. I would also pay attention to the nice and rich contrast that is missing in your image. Give it another try and come back, ok? Abby
