Seventh Son (2105)

Centuries ago, a witch named Mother Malkin was imprisoned underground  in a cage by Master Gregory, a spook (knights who hunt witches).  Now Malkin has escaped and plans to wage war on Gregory and the rest of humankind.  Gregory is looking for a new apprentice, seeing as they keep dying, and finds Tom, the seventh son of a seventh son.

They set out on a quest, with Master Gregory training Tom in the way of the knights.  Gregory is the last of his kind so he's looking for an apprentice to take over some day.  Since they all inconveniently die before this can happen, here's hoping Tom can survive long enough to learn the ways of the spooks.

Jeff Bridges plays old Master Gregory as if he's got a mouthful of oatmeal, a curious choice indeed as it's awkward and annoying.
