Meh. Paramount has always been a bit more uptight about fan films. Especially GOOD fan films. I feel like fan film quality is in direct correlation to how much the studios care. Haha.
Lucasfilm tends to be much more accepting of the fan film community as a whole and I can’t think of an instance where they pressed any kind of legal charges so long as nobody is making money. We haven’t really been given much of an indicator in these past couple years as to how Disney will handle fan films going forward, but so far they’ve kept relatively quiet which I suppose is a good thing.
I still hold that if somebody were to put the time, effort, and money into it, an entirely fan-made prequel trilogy could be made.

(come to think of it this could kind of be thought of as a rebirth of that early thread of mine)
That being said, once again, everyone feel free to spout off your ideas :p haha
