Cool ideas! Keep 'em coming!
My opinion on the whole age thing...
Have you ever seen a picture of any given old actor like at some ceremony or something? They look as old as they are. But with the magic of make-up, they could make someone like Mr. T (for Barret) look 37. I think that would be badass to have Mr. T as Barret, but Barret also has emotional moments like about the whole Corel thing. I think it would require a better actor than Mr. T. That's why I suggested Michael Clarke Duncan. He's a specatacular actor. And he's black. And he's huge.
My opinion about Orlando Bloom (sorry for the Orlando Jones thing. It was late when I posted) as Cloud...
One of the big reasons I cast Bloom as Cloud was his voice. It's exactly how I imagined Cloud's I-keep-to-myself voice. And my choice was strengthened by how they depicted Cloud in Kingdom Hearts.
My opinion about Leo DiCaprio as Rufus...
Actually, I think that would be a good choice. He's not a bad actor. The reason most people don't like him is because we were force-fed freakin' Titanic for a really long time and we're all sick of it. I mean, he pulled off a thug in Gangs of New York. But the little voice he's got actually wouldn't cut it for Rufus. Rufus is too powerful of a character.
Don't let this stop you! Keep the ideas a-rollin'!
