So far, the Twilight film series has overcome devastating personnel changes, crappy reviews, and subpar source material — but now it faces its most harrowing obstacle yet: restless leg syndrome! Intermittently factual supermarket tabloid Star is reporting that Taylor Lautner, who plays werewolf Jacob Black, is suffering from the debilitating disorder, which gives one the uncontrollable urge to move his leg muscles. Says Lautner: "I can never stop bouncing my knee …. People always tell me to stop, but I can't force it to stay still. If we're in the car, I'll end up shaking the whole car." He is so brave. We can only hope that Lautner's plight will attract more attention to RLS, so that we might one day find out if it's a real thing or not.
