After ''The Mummy Returns,'' it was beginning to look like we'd have a relatively bloodless summer. For all its rock & roll lancing, ''A Knight's Tale'' offered just a single fatality -- and that was from a heart attack. There were two more deaths in Jennifer Lopez's ''Angel Eyes'' (from a car crash) and one in Nicole Kidman's ''Moulin Rouge'' (from consumption). Believe it or not, the PG-rated ''Shrek'' coughed up two corpses for the summer body count: One went poof by spontaneous combustion, while another became dragon kibble. Now, as expected, the blockbuster war epic ''Pearl Harbor'' has raised the stakes. EW managed to tally 173 casualties -- and those are just the ones we could see on screen -- from gunfire, explosions, and drowning. All of which brings us to a running total of 256 for the summer so far. And Angelina Jolie hasn't even begun raiding those tombs yet.
