orson welles was only 50-51 years of age in this movie

Not only that, but he lived for another two decades.

When I saw this film, I blindly assumed Welles would be portraying an overweight Henry VIII (I know Henry wasn't always so, but I momentarily forgot.) So when I saw Cardinal Wolsey I was thinking "that actor sure looks a lot like Orson Welles" and only later, seeing Henry depicted as an athletic young man obviously not played by Welles, did I realize my mistake.
