TV Spot 4 - IMAX Trailer is actually Trailer 2 Imax version.
www.imax.com has 2 trailers.
Trailer 1 is the same version as Trailer 1 in the big list.
Trailer 2 is the TV Spot 4 listed n the big list part 2. It's a variation of Trailer 2.
That should fix the naming discrepancies. I think we should follow the listed .mov from official downloads.paramount.com, since the official Facebook site listed the same naming.
Now I wonder where/when TV Spot 6 became TV Spot 8. And I wonder where TV Spot 7 (the YouTube versions) originated from.

cheers
