From Ken Penders:
How Would You Like To Be In The Sonic Movie?
This one is being batted around, but if all goes according to plan, we could end up with a contest where some lucky guy and girl will each win a small part in the Sonic film.
Not only that, but we may also do a runner-up contest where a character designed by a fan may end up in one of the Robotropolis segments. Needless to say, any drawings submitted would become the property of the production, waivers would have to be signed, especially if we wanted to include them on the eventual DVD release.
At this moment, do not submit anything at this time. I will post all the information once all the details are ironed out. This is more or less to let you guys know the fans are being listened to, and we do want to involve you guys where we can.
Oh, yeah, one other thing: Amy Rose, Rotor and Antoine do appear in the script. They’re just not major characters this time out.
