Cool, one question though. I take it 35mm film used for movies is the same?? or is it different. If there are obviously more advantages for digital, why do people still shoot movies using film?
Everything posted above is basically 100% correct, but since my background is in cinematography I can field this one.
Certain films can do great purples, yes. And color accuracy generally moves less product than vivid colors move, so color accuracy is not as great a metric as one would think and not all films are made with accuracy in mind. Black and white isn't very color accurate, after all. But it's all weirdly complicated and boils down to aesthetic preference (unless you're an engineer and can understand this stuff):

Anyhow, motion picture film and still image film are different emulsions, though they are very similar and some films have been available as both.
Generally, slide film was considered "professional" for still images, and it has much less dynamic range than digital SLRs do and similar resolution. Most cheap point and shoot film cameras (and the films available at most pharmacies) are terrible by any standards. So the transition was quick for amateurs and professionals shooting 35mm film to go to digital.
Motion picture film is actually quite a bit smaller per frame than 35mm still image film, much closer to a 1.6X crop sensor that's then cropped to a 1.85:1 aspect ratio. (For super 35mm; anamorphic is a bit more complicated.) But it looks much sharper because it's in motion. Motion picture film is generally negative film, not slide film, which has very good dynamic range and still much better than even digital SLRs have. 5219, Kodak's latest, has 15 stops or more of dynamic range, though much less ends up on the final print. Some of Kodak's new C41 still image film (new Ektar) has inherited similar attributes, even if it's a different emulsion. For cinema, dynamic range matters a lot more because sets move so fast and struggle to contend with changing light...and if you miss the exposure, it's a lot harder to reshoot or bracket. Resolution is surprisingly bad. Movie film probably resolves around 8-10 megapixels at most, usually way less, and is usually scanned and edited at just over 2 megapixels (2048X1152) and printed at that resolution, too, so most movies you watch are just over 2 megapixels per frame.
Video is pretty close. 1080p video is almost 2 megapixels and most "pro" digital cinema cameras (even costing in excess of $200,000) shoot 1080p. But most cinematographers are used to working with film, and the pipeline in Hollywood is designed for it. Film post houses do incredible work with film and are less comfortable with digital. There's a built-in "good enough" you get by using film and for movies, dynamic range is still much more important than resolution, and motion picture film is designed with this in mind.
As things move to 3D, though, you can expect a lot more material originating on video for a number of reasons. Also, movies are still projected on film. Once that changes, expect more people to shoot digitally.
Also, fwiw, high-end cinema lenses are ridiculously good. Like absolutely ridiculous.
