Twilight Goofs - The Case Of The Missing Baseball -

As you will know, from watching the Twilight DVD special features, they used a clear Christmas ornament instead of an actual ball, to stop the actors from being harmed (vamps don't need gloves, frail mortals do!). Unfortunately it seems the post-production team forgot to super-impose the real baseball over the top in a few scenes! Hands up who will be looking out for that next time they watch Twilight!
