A saying off the phenomena that
George Lucas simply cannot keep his hands off his own original trilogy of movies. He has updated them with 4 separate incarnations of CG graphics over a 15 year span. This has created a frankenstonian mess of old film footage with high
resolution graphic composites on top. Therefore, the term 'Pulling a Lucas' just means that you cannot
stop yourself from updating your own successfully completed works and projects. It's the modern, 'if it ain't broke don't fix it'.
Dude, why did you update
that film (paper, render, car, suit, etc.) you created, it was
already perfect!? You pulling
a Lucas bro!
