I was reading a review of Jumper and read this part about Samuel Jackson which I had a good laugh at:
Eventually we meet Samuel L. Jackson, who is once again playing his bad-ass self, only this time he’s got white hair and a mean streak. (Sam Jackson cheat-sheet: If he has a ‘fro and a gun, you’re watching Pulp Fiction. If he’s limping, you’re watching Unbreakable. If he’s sweating and bluesy, you’re watching Black Snake Moan. If he’s wearing a brown robe, you’re watching Episode III.)
Here‘s the review for those who are interested.
