Revealing mistake: When Reese is leaving the dog cemetery, she brushes against one of the tombstones that has a stone dog on the top of it, yet as she walks past the dog begins to rock back and forth - clearly this is not a stone headstone. Pet cemeteries, just like human, have sturdy stone headstones to withstand the elements, not plastic.
Trivia: During the film's original outdoor reception Jake carries Melanie, who feigns death after having supposedly been struck by a lightening bolt, towards the wedding guests. Jake announces, "Melanie Carmichael is dead" but then a few seconds later he says, "Long live Felony Melanie." Jake and Melanie do this as a practical joke. The reaction of Melanie's mother at the supposed death of her daughter apparently upset the test audiences so much, that the production crew reshot the whole reception scene, minus the practical joke.
