So just to recap what seem to be some of the major variables that account for the film look (thanks guys for helping me think about this):
1) frame rate (24p)
2) grading in post (contrast, color)
3) all other aspects of film making. ie. acting, lighting, transparency of camera movement, audio
4) shallow depth of field
5) dynamic range (whites especially don't roll off in digital like they do in film, can be addressed with gradient filters / use of lighting)
What does (4) mean ? Is small DOF a cue for professional productions or the opposite ? I can think of two films even by the same director that use both (Barry Lyndon, especially candle lit scenes and others, shot at f/1.0 I think it was; but also The Killing, which generally features huge depth of field, if I recall correctly. Also--Hitchcock use large depth of field habitually).
One thing I noticed when I had my hands on a 7d: when I zoomed while shooting video, the zoom process itself, zooming in and out, looked phony somehow, like a painting in which the colors were mixing.
I agree with all the posted attributes of the "film look". For #4, depth of field does not indicate professional or non-professional. I've seen plenty of movies that have used DOF both appropriately and inappropriately (or so I felt, perhaps informed viewer's choice?). Some people think shallow DOF means high end or professional, but if you have a beautiful backdrop that you don't want to be fully or blurred out at all as it plays a role in the image, obviously you're going to use a long DOF.
One of the reasons your 7D zoom looks artificial is because it is manually controlled, it won't be as smooth as something controlled with a motor with a variable speed function. Also, keep in mind a lot of movies are filmed with primes, thus they aren't actually zooming, but actually moving the camera. If a movie "zooms in", look if the foreground and background are compressing. If they are compressing, it is zoom, if not, they're moving the camera.
So long as my memory serves correct, (5), dynamic range, is the amount of information stored between black and white. The higher the dynamic range (more F stops), the move "levels" there are between black and white, therefore more dynamic information. 12 stops of dynamic range (typical average of DSLRs from my research) is 4096 levels between black and white. 14 stops (which I believe is film) is 16384 levels between black and white, 4 times that of a DSLR, so whereas 1080P is 1080P, the amount of dynamic image information stored within those pictures will lead to dramatically different images. I would imagine there is some level of utilization of that information, perhaps if you only used the lower half of the histogram, you could achieve similar images with a DSLR, but one trained to use the entire dynamic range could achieve a more "rich" image. This of course is just my hypothesis...grain of salt and such.
