Saw Inception this weekend and really liked it. If you want to read a little more about some different interpretations of the film, you might want to check out these links: a solid article on Chud, one at Salon, an interview with actor Dileep Rao (who played the Chemist), and, at a glance, this handy chart showing who dreamed what.
Finally, here’s one of Nolan’s admitted visual references: this luscious scene of Fred Astaire dancing up the walls from the 1951 film Royal Wedding, shot by spinning the room and the camera simultaneously. You can skip ahead in this clip to about the 2-minute mark if you like.
