Actually, the cropping isn't done in the theatre, its done by the director and the editor in post production to cut the frames to how the director intended. They go through the negatives, and decide where to crop off, if the directors done his job, then the frame shouldn't really jump around the open matte negative and should cut off the redundant top and bottom.
I think with total recall, Mr Show Girls print, the one he supervised editing on, will be the widescreen one. The other will be done for TV/DVD by someone without his authorisation (if its anything like 90% of this crap happens). Thusly, the better in my opinion is by far widescreen (taking the assumption that the 4:3 takes the redundant matting), since the data in the vertical is redundant unless Mr Show Girls was doing a sloppy job, and the widescreen represents the human field of vision, its more favourable gain information in the horizontal since, that information is more 'useful' in representing what we should see and isn't awkward to view.
If he's filmed it with information happening at the top and bottom, then he's really messed up and zoomed in too far. I hate action happening at the top and bottom of the screen because you have to move your eyes up to see the info. As an experiment, notice how far you can see things to the left and right and up and down. You can see a lot further in the horizontal without moving your pov than you can in the vertical. I get annoyed when I see stuff happening that's just outside your vision and you have to move your eyes all over the place to see whats happening
Normally gives me a headache after an hour of it
edit:
some articles here I have read in the past and found interesting regarding the many formats.

Cameras capture in 4:3, there's some that don't now, but the cropped area was never intended to be viewed., that's the assumption I use. There are rare instances where the director didn't have an AR in mind and thusly the info isn't waste in the frame, in that case open matte is more favourable, even though it isn't as comforable to view (given it doesn't represent the field of vision, it is notably harder to view what happens at the top and bottom of the frame than the left and right).
Never Pan Scan though, that makes me want to vomit
I don't understand why anyone would do that to a movie
