Footage of Winona Ryder simulating sex and masturbation has surfaced on the Net to promote her new movie The Ten.

In the bizarre clip, Winona is seen doing the nasty with a puppet called Gary, prompting her non-puppet lover, Ross, to `beat' up his wooden rival.

In another scene, the actress pretends to relieve her randy wooden ’co-star' while driving a car.

The Ten - a re-imagining of the Bible's 10 commandments - will be premiered at the upcoming Sundance Film Festival in Utah later this month.

You can watch a puppet get wood below...if you're into that kind of thing...
