This is the one I bring up whenever someone tries to make the “George’s vision” argument. His true original vision was . . . a couple of extra rocks? More than anything else (besides maybe the door to Jabba’s Palace), I think this is the best illustration of how George was just changing stuff for the sake of changing it towards the end.
I’m still pretty sure any '11 additions were for the 3D release. Foreground rocks, deeper Jabba door matte, more poke-out-of-the-screen bits when R2 gets shot.
