I don't know the name of this film, the actors, or even much about the movie at all. Does anyone know the name of this film:

This lady finds a necklace and when she wears it ans says "shut up" time freezes. There is a scene where the lady is in a grocery store and is fighting with a woman of an item, she says shut up everyone freezes and she takes the item and even pays the cashier for her groceries by sticking the money in his mouth.

Any help would be great, this is driving me batty!! :(

Umm it sounds kind of like the never ending story (maybe the first, second or third I'm not sure) There is a necklace and when someone puts in on they control everything. A girl puts it on and goes shopping. Hope that helps.

It's an episode from the second "Twilight Zone" series (not the ones with Rod Serling or Forest Whitaker as the narrator) called "A Little Peace and Quiet".
