We can fairly get close resemblance of film colors if we process our digital photos in the Lab Color Mode instead of the usual RGB Mode in Photoshop.
First, convert to a different color space (Image > Mode > Lab Color). In Lab Color processing, the colors can be harnessed and controlled much easier because they can be separated based on their lightness in Channel A and Channel B unlike in the RGB Mode where controlling the lightness will also affect either the Red, Green and Blue channels.

Create another layer and this time a Hue/Saturation Adjustment Layer in order to fix the saturation and achieve a fairly natural colors. I prefer fixing the Red color first by sliding it to (-30) value, then the Yellow color by applying a (-20) value, then the Cyan color by sliding it to (-30) value then finally, the Magenta color by substituting it with a (-30) value. The values will of course depend according to your taste and may vary from one photo to another inasmuch as each may have different lightness.
