Heh, I am trained a bit in acting since I'm an animator as well, and I've actually done a little ADR work for my game, so I can voice act as well. We'll have to determine if whomever we get will work or not. Go figure, this would end up being AMV Salad: The Motion Picture and we'd STILL follow in AMV Hell's footsteps in that regard, haha!
I wasn't considering that we'd use actual Family Guy clips as the asides, but for a quick example of what I meant, say we chose Beck as the base anime:
Ryuusuke: "If we're going to get 'Shiny Happy People' out there into Live Houses, then we-"
Taira: "I thought we were called 'Beck'..."
Ryuusuke: "Hey, who's the leader here?"
Taira: "...this is looking even worse than that last band I was with..."
*cut to the Haruhi clip playing Dragonforce from AMVS2 but a composited arrow pointing at Nagato saying "Taira" or something*
That's not very funny a cut of course, but for example purposes, the idea was basically take AMV Hell style clips (I was thinking new ones, but they can be older as well), maybe even request from creators to use some of the ones we like, and make it so that AMV Salad still exists as a random clip thing, but give it an actual plot with the clips inserted as Family Guy STYLE asides. This way we have unlimited aside ideas and people can come up with whatever they want. It will also limit the amount of time we have to land those jokes so we'll be forced to be creative. Darkness would be perfect for those, those appear to be his strong points if you can get him interested (I've always loved his clips, you can probably see the similarities in his style of humor and mine, actually.)
The one drawback is there would have to be that the writing would have to be exceptionally good. We have enough bad fanparodies coming out in recent years. The jokes have to be excellent, and the story purposeful as well, so ego would have to be out the door and we'd need a test group to tell us if it sucked before we ever proceeded. I've been a writer for years, and if you truly wanted to do this Deuce, I'd love to help out as a sound board for ideas and editing (both written and video ^^).
