If you go to a AMC/Cinemark/Regal (most of the US) movie theater, you will see an campaign backed by Sprint reminding people to turn off their phones, with the tagline "It takes a lot of phone calls to make a movie. And only one to ruin it." In one particular ad in this campaign, the topic of the calls between the moviemakers and the creators is whether a cartoon hedgehog should be wearing pants. The aforementioned "only one to ruin it" moment comes when the animators, fed up with the time consuming project and senseless bickering, put pants on the hedgehog...and leave the fly down.
