Making a sexy math movie is hard. Kate Bosworth helps.
We've got a new theatre here in downtown Toronto, and they're offering students from my university free admission on weekends or something. So after work I went in and saw 21, which isn't very good. But the theatre itself is interesting. All the theaters have digital projection, and the resolution is good enough that I didn't notice the difference between them and celluloid except during one particularly fast-moving shot when there was some motion blur. (YMMV.) What I did notice was the lack of cue marks. Somewhere, George Lucas is happy.
