I'm making a stop-motion film using various different puppets including action men. In a few of the scenes the action men are dancing (swaying side to side) and I need them to sing. I was looking to achieve this effect by filming a person singing and placing their mouth over the top of the action mens mouth.
I forget what it's actually called, but you can google a process called "head replacement" or "face replacement" that was used on a recent (within the last 2 years) music video parody: it featured video from The Golden Girls, with a guy's face on the ladies' heads.
