Hmmm, Honor or Allistair, tough decision...Frankly, I couldn't care less about the other series, I'd be happier if there were more effort put into the mainline series.
As for who would play Honor in a movie, I refuse to participate in that speculation, since people with absolutely NO taste in decent actors have abused the concept beyond recognition on Baen's Bar for years. About the 20th time you see someone insist that no-talent freak Angelina Jolie would be the PERFECT Honor, you just kinda have to throw up your hands in disgust and give up on the whole idea.
BTW, for those with the excreable taste to embrace the idea of Angelina Jolie as Honor, you can forget about it. Weber has repeatedly said that any film adaptation of the HH books he contracts for will have a clause written into the contract stating that she isn't allowed to touch the project. He's still slightly miffed that his post-9/11 attempts to adopt a Cambodian orphan were handled as though the baby would be fire-bombing the Washington Monument the moment it arrived in the US, whereas Jolie practically had her orphan delivered to her movie set as though she had ordered Chinese takeout.
"Is it wrong for me to long for the simpler days of yesteryear when performers weren't so confusing? Jagger, Bowie...you KNEW they were women. But nowadays, this internationally ranked cheerleading coach just can't figure it out. Neil Patrick Harris? You confuse me. I HEAR you're gay, but there you are on my TV playing a normal, womanizing, cardigan-wearing straight. That's confusing. And then I heard a rumor you're not actually a doctor. So much sneaky gay deception!" --Sue's Corner
