And seriously, I'd argue that the big D is more suited for movies than television. For one thing, the ship is very wide so that would fit perfectly with the theatrical widescreen ratio.
The E is the one built for a widescreen look, the D is practically so squat it is 4:3 like TV was for so long.
Honestly, if GR hadn't castrated the nacelles on Probert's original concept, it would have probably been fine instead of something I have always hated.
What? Andy told me that the books have the caption backwards re the final design. He originally had the nacelles shorter, so that the pylon and nacelle would mimic the silhouette of the saucer and the neck, and Gene's two comments on the design were "make the engines longer and put the bridge on top".
