I could be wrong here, but I get the feeling the original poster isn't thinking of this is ontological terms, i.e. the aesthetic and medium of "film" as a distinct from the aesthetic and medium of digital. Rather, I think the poster means "film" as in "cinema." If you look at the flickr profile he linked to, most of the categories refer to "cinematic this" and "cinematographers of that."
In other words, I think he means the pictures are evocative of modern Hollywood cinema, and that he wants to know how to replicate this look.
If I'm right, here are some observations:
The flickr photographer does him/herself some favors by starting with compositions that suggest narratives. If there's action in the shot, for example, he/she often frames it from a semi-wide angle, accentuating leading lines and depth and motion through space. Other shots create a sense of mystery or foreboding by isolating a transitory figure within the environment, again with the help of leading lines and balanced compositions.
That much is done in the camera but a lot of the effect was created in post. The images have been treated to emphasize shades with certain relationships on the color wheel. For example, many of the images push the shadows toward the blues while nudging the mid tones toward the reds. This isolates skin color, making subjects pop, and, by boosting opposed colors, creates greater contrast in the image. Others suggest warmth with green and yellow/red casts. Whatever the combination, it should be noted that this effect can be taken to extremes very easily.
Speaking of contrast, the flickr images look like the blacks have been crushed a bit. Generally, the darker areas are pulled down just enough to retain detail. Highlights are pushed, meanwhile, pretty carefully to increase contrast while still maintaining detail and subtle gradations. There are a number of ways this could be accomplished. If you shoot in a neutral profile, you might get a similar effect by simply applying a typical S-curve. In a standard profile, one might apply a less aggressive curve and then selectively bring back highlight data, etc. Depends a bit on how much you want to mess with colors or make local adjustments, among other things.
A lot of the images are shot in fog or snow, which applies a diffusion effect to the lights. That's something that could be created practically in a studio-style shoot but that's harder to control if you're a street shooter. Red Giant makes a Magic Bullet plug-in for Aperture, Photoshop, etc. that allows for the contrast, color and saturation work I described above, and that also allows you to apply various diffusion effects. It also has tools to make sure you don't overcook the image, such as scopes to make sure skin tones stay where they're supposed to. It contains a number of presets, most of which look overdone unless you shoot in a pretty flat picture profile. But once you learn what kind of acquisition data it needs, the program is pretty much designed to quickly and easily produce the specific look you're pursuing.
