OK, well for a start, do not go down the route of the stereotypical dynamic duos. They are way overdone and are often the subject of jokes throughout the community, so that's a no-go. As far as making it original goes, write a good script. At the beginning the whole point of dynamic duos were their chemistry, complimented with some witty banter and generally well written dialogue. Admittedly that's a fairly big expectation, especially when your characters are plastic LEGO men, but your grammar seems reason enough to believe that your vocabulary is wide enough to be able to do so. Good luck anyway.

OK, well the best thing to do for voice actors is go to the Audio thread and post a casting call. Check out some others there first, usually you can get a vague idea of what's needed, i.e pictures, test-lines, info on characters, etc. As far as popularity goes, the most important thing is to make it good. The better it is the better the feedback is, the more likely people will like it/favour it, and so on and so on, you get the gist of it. And of course, it's also a combination of luck. Just remember - popularity isn't the most important thing, so don't worry yourself, the greatest gratification is the feedback from your peers.

Hmm perhaps I could introduce more characters to the series..a "Sitcom" if you will. Then maybe it would stray away from the typical dynamic duo.

Haha its funny you should mention the animal, because one of the characters lives with a pet pig. and Yes I am up to 4 characters as of now, don't know if I am going to go any higher. I have the voice actors for 3, still looking for a 4th, and if I seem to find someone else willing to join, then I am willing to raise the characters list. Although I have all these characters, the main focus will be on the two, but every episode will include some of the others.

Man, That would be much appreciated, and don't worry I don't think any recording is getting done until Saturday I been hard at work on this script. But I will definitely Give you a part, now are you wanted to just do this one episode, or can I give you a permanent part?

Sounds good
