Within the last couple of years, Canon has developed a line of DV camcorders that use a technology called "Progressive Scan", which means they shoot 30 still frames per second. This gives the video a film look, opposed to the video look, which uses two interlaced fields per frame. Using two fields per frame is what gives video it's "smooth", video-like feel.
Although the footage playes like film, it is very clean, and doesn't have the dust, dirt, and scratches associated with some of the industrial film gauges (16 and 8). However, you can use After FX with a plugin called DigiEffects to simulate just about any film gauge imagineable.

Good luck!
p.s. Shooting on actual film provides more color depth and resolution than video can provide (in the lower gauges).
Changing the FPS from 30 to 24 helps to give the video the proper speed of film, but to achieve the "film look" you need to combine the fields into frames, which I think can be done in Premiere (not sure).
Good luck!
I am writing an article with illustrations and movies for filmlook techniques at the moment. Please drop by http://www.exposure.co.uk in a couple of weeks to take a look.
#1>>> You have to light it like film first... I worked on a project @ Jim Henson (Wandering Monkey) that was shot on digital beta, they forced depth with their lighting, we shot a shootout in an alley and they made layers of darkness and pools of light down the alley, it looks great! The Film made Sundance, it is called "The Item" it is a dark Comedy like Peter Jackson would do (they are HUGE fans) it may play on the Sundance Channel on cable, look for it.
I think that there's a "deinterlace" filter in Photoshop, so you can get better looking video stills.
