It sounds like your friend has an early release from just after they decided it would be profitable to release Star Wars outside of the main market in southern Bolivia. The picture isn't really tilted. You just need to view it with the next generation of 3D glasses, in which the left lens is made of blue film polarized at 45 degrees, and the right lens is made of red film and linked to a camera mounted on the ceiling. If you had those, the picture would look normal. At any rate, your friend should hold on to that copy; it'll probably be a collector's item some day. ...or maybe it's a bootleg. — Ray 11 hours ago
