I never got "homely" out of Weber's descriptions of Harrington at all though the rest looks accurate.
If for some unlikely reason Jolie wanted
to do these films, she'd be the actor playing Harrington in an instant - and if she doesn't there's probably not enough money tied up in this to make that happen. Popular as HH is with sf-fantasy fans, Weber doesn't have the sales figures to give him Rowling-level clout or veto power over casting, etc. unless he's negotiating with a very small production company for a relatively limited amount of money. We'll see what we'll see.
