Just watched the Illusionist again last night. One of my favorite movies and highly recommened.
You should check out The Prestige if you liked The Illusionist, two of my favorite movies.
Last week I bought Let Me In on the Blu-Ray and I've watched it three times, it's a great movie and I'd highly recommend it (as well as the original Swedish version, Let the Right One In). A few nights ago I watched Insomnia on Netflix which is a Christopher Nolan film starring Al Pacino and Robin Williams, it was also very good. Most recently I watched Zodiac directed by David Fincher, which was quite good but a tad slow in parts.
I'm always on the lookout for great movies that I haven't seen yet, I been actively scouring Netflix for some movies that I might like this week.
