House Finale shot on 5DII's...."It's the future."

[piiooo]

Still videocameras used for films are a LOT better than the 5D. I can't imagine they would use a 5D for a serious cinematic movie.

Yes, but I think this is aboutthe size of the sensor, at which 5DII is better. Thanks to cameras like 5DII a razor thin DOF is possible.

I mean 1080p full-hd sounds like a lot...

1080p is actually "only"2 megapixels, which is obsolete for still picture, butonce you move it at 30 or so fpsit becomes a verydemanding format.

...but professional cameras use a much greater resolution.

And yes, professional cameras use higher resolutions, to the point that they able to achieve panning effects in post. Canon 5DII uses most ofthe surface of itssensor to record and then downscales theimageto1080p.

And I'm not sure what resolution cinemas render, but I'm guessing it's greater than 1080p.

I am not sure here. But remember, we watch movies in the theater from quite a distance, so I would not be surprised if it actually is 1080p. Maybe next time I go to a movie theater I sit in the first raw andtake a closer look at those pixels[:P]
