mute wilma

There's something odd about the closing credits from the first season of The Flintstones.

As Fred walks by Wilma, who's asleep in bed, you can see that she has no mouth.

Joe from my cinema history class gave some background. When they were animating the Flintstones, mouths were done as separate cells from the rest of the person. That made it cheaper to animate people standing still and talking -- they could keep the same image for the body and just change the mouth. For whatever reason, in the sleeping sequence they neglected to add Wilma's mouth.
