Douglas Fairbanks Jr

It must have been difficult, at least in his early years, living in his father's shadow.  Douglas Fairbanks was an amazing athlete and bursting with life.  To see him in Black Pirate doing all his own stunt work

it's simply extraordinary in any era.

But Douglas Fairbanks Jr. was extraordinary in his own right.  Beyond being a good actor, he was a thoughtful, intelligent man, a decorated Naval officer with many years of service to his country, well after WWII.  His two volume biography Salad Days is definitely worth reading, written by himself, his good humor and wisdom shines through.
He was also a damn fine looking man as proven in this George Hurrell portrait.
