Essay for the pop culture site, 13th Dimension: http://13thdimension.com/george-reeves-a-birthday-appreciation/; an excerpt:

"Reeves might’ve been even better as Clark Kent than he was as Superman. His Kent wasn’t the bumbling oaf/newshound nerd that we’ve come to expect since the first Chris Reeve movie—he was as confident and resourceful as Superman. And certainly no wimp. Reeves, cutting quite the masculine figure (remember his dashing self in the beginning of Gone with the Wind?), was no doormat for Lois Lane. No one’s done Clark Kent better, in any medium. And no one’s ever done that last-shot wink-and-a-smile like Reeves patented.”
