The summer movie season now officially begins in early May, thanks to last year's blockbuster May releases: Spider-Man 3, Shrek The Third and Pirates of the Caribbean: At World's End. This May, there are no fewer than 23 movies coming out, including "tentpole" films Iron Man, Speed Racer, Narnia and Indiana Jones. And the schedule is overcrowded with wannabe blockbusters all summer long, raising the chances that we'll see some high-profile flops. [Variety]
