You mean theaters. Screen count is different from theater count. Spidey 3 was on 10,000 screens at 4,252 theaters. TDK was on 9,000 screens at 4,366 theaters. IM2 will probably be on 10,000+ screens since it's early May and there aren't many other movies that audiences want to see right now.
The first Iron Man opened in 4,105 theaters on 8,700 screens. The 4,000 theater thing is probably just an early estimate. I would think the actual theater count for IM2 will be more along the lines of TDK (nearly 4,400 theaters) while the screen count will be more along the lines of Spidey 3 (10,000+ screens).
