Though more filmmakers are using DSLRs nowadays, many still want their footage to look like it was captured with film and not digitally. Digital DSLR cameras with more dynamic range can help you achieve the cinematic film look, though it requires color correction in post.
You can also produce pretty good results and even create presets with video editing software like Sony Vegas PRO, Adobe Premiere and Final Cut Pro by controlling the grain, amount of saturation, white balance and color curves.
Other options to achieving the cinematic-look is by using older vintage lenses. A worn-out lens that is not too sharp may actually add the right amount of grain (or noise) seen in traditional films.
Lastly, remember that many factors such as: Lighting, Camera movement, Audio, Depth-of-field and Aspect ratio - play an important (sometimes overlooked) role in producing video that looks like film.
