1 Obi-Wan: It's over Anakin! I have the high ground.
1 Anakin: You underestimate my power!
2 [sound]: Whooom! Sliiice! {Anakin attempts to leap over Obi-Wan, who slices his arms and legs off with his lightsabre}
3 Obi-Wan: And now you haven't a leg to stand on.
4 Anakin: You and your damned aphorisms!
4 Obi-Wan: Actually they were just cutting remarks.

Of all the bad lines in all the Star Wars films - and there have been a few of them - this one is my candidate for absolute worst.

Obi-Wan: It's over Anakin! I have the high ground.

He is literally standing on ground that has a greater elevation than where Anakin is standing. But it's also the end of the duel, and Obi-Wan has won because he is on the side of right and good. He has the moral high ground too. Get it? It's such a subtle nuance that you could be forgiven for not noticing it...

Hmm, now that I think about it again, that's bloody brilliant.

Oh, and in case you're wondering how I did the effect of Anakin suspended in mid-air, there was no digital manipulation trickery involved. I simply suspended him in mid-air exactly as you see and took a single shot. He's held up by a strut made of Lego parts, all of which are cunningly hidden behind his body.
