He is NOT looking for ideas right now - he has plenty of those. So no "you should make a movie about the feral cat population in Seattle" or whatever. He's looking for things like "I filmed 4 hours of stuff at my sister's wedding and now I have no idea what to do with it" or "my bellydancing troupe would love to have some performances filmed and made into a promo." Stuff like that!
If you'd like help with some sort of film project - go hit up inventionsleeps or email firstname.lastname@example.org - because he's a genius.
