Q: Hallo there I am sorry to bother you but I kinda need a little help and gaudiness. I have an idea for an animation film but I can't really show it to anybody without having a manager or an agent first and I have no idea how to do that. Can you please help me? Thanks very much.
A: Just like the studios and production companies you'd eventually like to reach, most reputable agents or managers are uninterested in "ideas," especially from unknowns (I assume you're an unknown, if not, what the heck are you doing asking a question like this to an unknown like me?). They're much more likely to respond positively to a well-written query in which you very briefly describe your idea and then offer to send YOUR SCRIPT. That's right, I said script. Aside from claiming a recommendation from J.J. Abrams (don't do this unless you really have one), writing a script is the only way I know of that you, currently an unknown, will get a legitimate agent or manager interested in your "idea."
As far as your needing a little gaudiness (assuming that wasn't an autocorrect error), I'd suggest checking out Mardis Gras or carnivale footage on YouTube and seeing if you can crib some tips from there. ;)
Got a question for a self/traditionally published author and TV animation writer (who'd be perfect for that show you're staffing)? I thought so. Leave it here in the comments and I'll try to answer it on the following Saturday.
