And don't forget the guy who played Frodo. Apparently, he's taller in real life. The real thing is you have to find someone with as strong a personality as Honor, and I think Makeup can supplement the appearance fine enough. Plus, it would allow for a market of Manticoran and Grayson uniforms. I want a Grayson one.
I'd bet that the Shiva Option trilogy would be better in theares than the Lord of the Rings was. Probably just as long, too.
