Just watched "Returning to Jedi' on youtube. Excellent documentary.
It got me thinking about how small ROTJ felt, considering its the huge conclusion. It seems that all these nifty things were shot, but not used.
-Madine's death.
-A female rebel pilot
-Three Pruneface aliens (I totally had that toy) in the Rebellion
-The infamous sandstorm.
I doubt the elements are available to add these, but this additions, probably less than 2 min of screentime, might have made the film feel much more expansive.
