I actually think of this kind of stuff quite frequently! For my OC bounty hunter / space pirate Dez, it would probably be Joe Duplantier, a French metal singer. For Madison, an Irish/Scottish redhead, one of the actresses from Black Mirror would be perfect. And for Felix, well, his face was inspired by a model named Sébastien Andrieu, whose voice would also be perfect. 8D I think about "who would play them in a movie?" too quite frequently, but am so picky about faces and bodies and everything... xD

@nyreen: You should definitely do it, it's lots of fun! But yeah, there are simply so many people to choose from, and it's impossible to find them all. I'm of the belief that there's gotta be someone out there who looks the same or at least similar, since we apparently can't image or dream of faces which we haven't seen before.

So true about voiceovers, too. I think if, in some wild alternate universe, my story were to ever become a movie, I'd prefer CGI with voice acting, since it's easier to alter someone's voice or have them do an accent than it is to alter their appearance consistently. Plus, CGI would allow the characters to be represented in their pure/true form without the constrains of physical actors or, well, real life physics getting in the way. xD

@nyreen: Exactly! Not only that, but producers are greedy butts, and wouldn't want to support your production unless they can control certain aspects to make it more "marketable"--adding certain actors/actresses for more name appeal, adding cliche' romance or tragedy plot points, the list goes on and on.

I just need Ridley Scott to hang on for a while longer so I can have him direct my material. xD
