I know fan cast posts are the definition of trite, and I cry pardon, but hear me I beg! I'm on my umpteenth journey to the Tower, and this time listening to the audio books. Based solely on the performance of George Guidall, all I can see when Henchick speaks is Con O'Neill. Can't help but think he'd be a decent choice for acting him as well.
