Just a few little points that i wanted to bring up..

with some people talking about inconsistencies between EPs III + IV
I've found one in just ANH

In the Cantina when Ponda Baba (the walrus man) grabs Luke's shoulder, his 'hand' is a fingerless flipper. When Obi-Wan slices it off, it turns into a furry hand!

Another point is in the Compactor scene, how did that huge metal pole get there? I imagine a Stormtrooper talking to his roommates..
"Hey anybody want this huge pole? No? Alright, i'm just gonna chuck it away then!"

Finally, In ROTJ, As Jabba watches Luke's hologram, smoke from Jabba's Hookah defies physics and starts flowing down for a shot then flows up again in the next one.

these are just some things that amused me,
and I welcome any comments!
