Jurassic Park taller IMAX version?

[Riddhi2011]

This is how Jurassic Park would look in a 16:10 aspect ratio , in the IMAX screen(15/70) (all sources are 35mm):

This is a shot that looks particularly impressive when the mattes are opened-up.

You can fully realize the fact that I've merged two images into one, and in paint because I do not have photoshop installed (My Graphics Card is creating problems).

Looks better in my opinion than the cramped 1.85:1 version where Grant and Lex's head's are threatening to be cut off the top edge.

Has the same impact, except its slightly taller.

5. And last but definitely not the least-

The Rex's eyes at the extreme top edge of the frame makes the widescreen version look distracting, whereas the framing on the Fullscreen DVD (the source for the top image) looks much more soothing to the eyes and the Rex looks better in that(my subjective opinion) framing.
Also the top image has lost a bit of width from the widescreen because that's how the 4:3 version was framed, but the original 35mm negative should contain the Full aperture image, which was not a CG shot.

NOTE: The Black Bars roughly represents the space that will be left unoccupied in the 1.44:1 15/70 IMAX screen. This is a close approximation!

There can be another alternative- framing the movie in 1.66:1 which is slightly shorter vertically (Django, most European movies, and the IMAX version of Apollo 13) than 16:10 (1.53:1 probably?)
