Damage.

Rule #487: If you name a character “heels,” her heels will break in the middle of production.

For example: During the filming of Star Wars, it is rumored that the death star they were using “blowd ups – fa shizzle.”  This forced Lucas to write the explosion into the film.  In the original version of the script, they leave the death star, and the film ends in a dance number. (might not be true)
