My gut feeling about sequels is that they should be premeditated: You should try to write a trilogy first or at least sketch out a trilogy if you have any faith in your film.
Don't listen to those who say, you taking too big a chance. Michelangelo would have painted the Sistine floor, and it would surely be rubbed out by today. Most important, don't listen when the little voice of fear inside you rears its ugly head and says. they all smarter than you out there. They're more talented, they're taller, blonder, prettier, luckier, and they have connections. I firmly believe that if you follow a path that interests you, not to the exclusion of love, sensitivity, and cooperation with others, but with the strength of conviction that you can move others by your own efforts, and do not make success or failure the criteria by which you live, the chances are you'll be a person worthy of your own respects.
If you go to Sundance, the experience that I've had there as a viewer is... there's like a hundred movies there, and you've got to figure out what movies are sold out, what can you see. Sometimes you go to see movies that you don't know anything about because it just works into your schedule.
