Well, yes, you can watch 3d movie even you have astigmatism. And in my opinion, when you just have a pair of contact lenses which can do a good job for you when you are watching 3d movie. In common, glasses generally rely on dramatically differing lens curvature and thickness which can throw off the distortion effect required for traditional 3D. But on the other hand, contact lenses can balance your eye dominance issues then glasses. And in that way, the thickness and curvature variance negligible to naught and 3D glasses always work fine with contact lenses, even when you have astigmatism. So you can just have a try.
