Character mistake: In the final scene, one of the newspaper clippings on the killer's office wall reads something like, "Huge Mudslide in Mexico: All Killed Expect Newborn." The penultimate word should be "except." (01:35:55)
Character mistake: At the memorial service the principal says that it's been 39 days since 39 loved ones had died. But there were 40 students on the plane and 4 chaperones, making the total 44. Now 7 people got off the plane, which means 37 people related to that memorial service actually died, not 39. Two pilots would make up the numbers, but there would be flight crew too, which still leaves the numbers off.
Character mistake: When Boris and Natasha (Jason Alexander and Renee Russo) are at the airport (just missing Rocky, Bullwinkle and the FBI agent) Natasha says something about "Moose and Squirrel don't even know our names", yet earlier in the courthouse scene, Bullwinkle says something about Boris and Natasha being real people and Rocky and Bullwinkle still being cartoons.
