After ”Pearl Harbor,” we thought June would create a lull in our summer-long tally of on-screen deaths. But count on John Travolta to pile up the corpses: ”Swordfish” dispatches a whopping 25 by gunfire, car crashes, and bombs (including one woman detonated into tiny pixels). Meanwhile, ”Evolution”’s aliens beam up 26 humans, including several smooshed by a giant appendage. Even Disney’s animated ”Atlantis: The Lost Empire” ‘toons out four, three of them overtaken by the mystical light-beam-like Heart of Atlantis (and we’re not even counting battle scenes and a flood that sinks an entire civilization). The count so far? 311. Glug, glug.
