Please feel free to comment and let me know if you think someone would be a better fit for a part! Still working on this one!
EDIT AUG 28 - Thanks again to the folks at Goodreads for suggesting some actors/actresses for some of these parts!
Thomas Seymour - Jude Law
Henry VIII - Ray Winstone (He did so good when he played this role in another movie and he could pull off a very sick and fat Henry!)
Edward VI - Freddie Highmore
