Alien Monsters Pull Crying Woman Down Toilet

I remember a scene from a particular movie that involves an intergalactic space cruiser overrun by horrible monstrosities.

A woman locks herself in the bathroom and is weeping due to the death that surrounds her, when she is suddenly pulled down the toilet by one of the creatures. Blood is sprayed everywhere and her last dying screams echo throughout the halls.

What is the name of this movie?
