I think most people still limit their imagination to crappy Star Wars fan films (bit weird tbh... there's enough "lore" by now to make something superb even out of Star Wars).
But the qoute sums it up. In fact, it's *any day* easier to "sell" a fan film than ANY original idea -- because, there's no such thing as original ideas anymore. And if it is, those ideas never leave the local theatre festival screening.
