The back of the V2 midsoles are actually more accurate to the movie. Are you going to have RD midsoles with movie accurate everything else? I believe the reason they edited the back of the midsole for the 2011s is that that part of the shoe would get a lot of friction when walking and wear it down a lot if it stayed like the movie version. More practical.

the v2s soles are too high at the back by at least 1cm and still not accurate. Add to that the heel cup which is too small in height by at least 1.5cm.
If you drop the height of the v2 soles at the back, the heel cup becomes too low, it needs to be made bigger, so thats another issue in itself!
I've looked at numerous pictures from all angles and the v2s are still not same as the movie versions.
There is not much difference between the RD version and 89 movie shoe back sole height.
Its actually the clear soles which are slightly different towards the back edge of the soles. The RD version goes much closer to the back edge of the soles than the 89 movie version.
The toecap height on the movie version is also maybe slightly bigger by a few mm.
The actual heel cup on the RD version is also different to the 89 movie version. The RD version seems to have a bigger "arse" lol, it sort of droops down more.
Another difference is the square section of the uppers thats level to the bottom line of the triangle cutout, on the movie version its straighter, while the RD version is slanted.
Trust me, ive studied these things inside out !
