Ugh! This sounds exactly like pseudo-context as described by Dan Meyer (http://blog.mrmeyer.com/?p=8002). There are so many awesome things to inspire someone in math, and slapping a popular movie character on rote drills seems like a misguided approach to motivating the challenge. I mean, on the one hand, good for you if you can find some trappings to make doing drills more fun. But while you're getting them to exercise skills, you're really missing out on the deep and fulfilling motivations that exist for math!
