In the ending credits, it says: "no animals were harmed in the making of this film however, we did manage to sprain two ankles, break one wrist, squirt one extra in the eye with chili and drive our upm into insanity".
In the opening number of the show at the end of the film, Kelly's character Helena sings that she loves Burke's character Lysander, when in the original play, Midsummer Night's Dream, Helena loves Demitrius.
In the bench kissing scene, the editors decided to digitally remove the beer bottle from Kelly's hand. They didn't replace it with anything so it looks like she has a deformed claw for a hand when she walks to the bench and sits down. Later in the scene, the bottle is off to her left where there was no bottle before.
