Palpatine bending Mace Windu's lightsaber blade - yes or no? (The movie)
So here is a gif and a video of the movie:

We see that the tip of Mace's blade wavers back and worth. Those on Sidious' side argue that because only the tip was moving, that would mean the blade was being contorted. Those on the opposing side have offered the counter-argument that Mace was actually moving his hand in a small circle, creating the illusion that the blade was wobbling. Personally, I don't see it no matter how hard I look, and I certainly don't see the fountain of the blade moving, only the tip.
To settle this once and for all, we'd need a scene-by-scene deconstruction of every pixel on-screen. I am not that good at editing, so I'd ask someone else to do it instead - to settle this hotly-debated topic for good.
