A tipster just sent us a link to a new behind-the-scenes video from in-production Twilight sequel New Moon containing actual footage of star Taylor Lautner's suffering from what appears to be a serious episode of Restless Leg Syndrome (if you haven't been following our coverage of this tragic story, catch up here). Skip ahead to 1:30, where Lautner and co-star Kristen Stewart seem to be waiting for his spasms to subside before they shoot an important scene in someone's garage. He is so brave. Warning: Some viewers may find the images in this video disturbing. Click to watch!
