How do I use adobe photoshop to turn photos into cartoons like they did on the movie A Scanner Darkly?

Question

These photo stills from the movie show the type of effect I would like to make.

Answer 1

If you have Windows Movie Maker, there are some film filters that you can use, such as Watercolor or Swizzle Stick

Answer 2

Try Filter>Posterization and vary the filtration level. I DOUBT you can really do this unless you have a monstrous movie budget where they fake stuff that computers do all the time, but this looks like it's a start. If someone gives the right answer, I'll be the first to admit I'm wrong and we'll both learn something.
