you can always convert it to 24fps, although some movements might look a bit weird.
video looks way sharper than film, so what my editor used to do when we shot films with an EX3, is that she'd duplicate the image, overlay, and lower the opacity to look softer. very subtle difference, but its there.
lights are also softer on film, and i noticed another editor of ours adjusting them with "glow" and "bloom", i think.
EX:
turning the saturation down a bit, and adding a bit of grain helps too. i'd recommend Magic Bullet, but i usually avoid using it because its a bitch to render.
