I just watched the movie Season of the Witch with Nicolas Cage and Ron Perlman. I liked it a lot, though it certainly wasn't perfect. In any case, if you are a fan of Warhammer Fantasy Roleplaying, you should watch this movie. It's pretty much a perfect fit.
Dark woods, knights, knaves, and evil magic are all present. A witch is escorted in a cage/wagon to her trial at a monastery. She uses magic to foil her guardians (or maybe she's an innocent being framed).
Some of the special effects weren't great, but I liked the combat scenes, and the banter between the various characters.
