Re: Blu Rays Aspect Ratio Question
My choice would be 16:9 with minimal cropping. There are a few ways it could be done - CG to remove the lights and stands at the edge of shots, CG inserts to extend the frame where necessary, new SF shots (not too hard with extending the starscape background for space shots), subtly stretching the edges of shots and as a last resort, cropping.
Some of this would be expensive, but as digital tech gets cheaper it will become more viable.
Soon oh soon the light, Pass within and soothe this endless night, And wait here for you, Our reason to be here...
