We are about face a slew of 'big' movies coming out, most of which are the third in their series, namely:
The Mummy 3
Shrek 3
Pirates of the Caribean 3
Spiderman 3
Rush Hour 3
Ocean's (1)3
Bourne 3

Also upcoming is:
Fantastic Four 2
The Hulk 2
Harry Potter 5
Almighty 2 (Evan this time, not Bruce)
The Simpsons
The Transformers

Come on guys, you in the second list need to keep pumping out movies to catch up! (Except for Harry Potter, of course.)

Any big ones I missed?
