This is my first post here, yay for me!
I think in addition to picking my favorites I'm going to offer my opinions of several of the other actors as well.
I should preface this by saying I'm definitely not a Superman expert, though I wish I were. The first film I saw was Superman II, then Superman Returns, and Superman. I have not seen III or IV and have been advised not to even bother with IV, haha. I've seen a few of the Original Superman series with George Reeves and only discovered L&C last weekend and am now obsessed with it! I watched Smallville during it's first season but it failed to keep my interest.
There, now that that's out of the way, here's what I have to say.
Superman: As far as this character goes it's really hard for me to pick. I think for me it's Chris Reeve. Dean is adorable, no doubt but as several other people have mentioned he seemed a bit awkward or tense in the spandex. There's definitely a special place in my heart for Brandon Routh, he's what drew me to Superman in the first place and I like that he's drawing new and younger fans to the character, such as I.
There's something about George Reeves as Superman though that I find appealing. The idea of Superman may still be an American hero but they seemed to have moved away from the idea that he's "Mr. All-American", fighting for the "American way". I think for the time, George Reeves was a perfect Mr. All-American and did a great job portraying the then-ideals of Superman.
Clark Kent: Dean definitely wins this one. George Reeves was way too suave a Clark for me and Chris was not so much mild mannered but... dorky, lol. I think Brandon did a better job of playing Clark than Chris did, but Dean was the only one who was able to give any depth to the role. I hate Tom Welling as Clark.
Lois: I really didn't hate Kate Bosworth as Lois. When I found out she was in the film I cringed, thinking she was going to ruin the movie for me as Katie Holmes did to the newest installment of Batman movies. But I was pleasantly surprised. I think she captures the look of Lois better than anyone else, but she fell a bit short on portraying her personality. I think my pick is a tie between Margot and Teri. I first saw Teri on Desperate Housewives and only recently started watching L&C so it's hard for me to grasp her in the role of Lois just yet but she does make me laugh a lot.
Lex: While it's interesting to see how Luthor evolved into what he is, as Rosenbaum has portrayed, he's on the bottom half of my list, mostly because I just don't like Smallville. John Shea is a good villain but it really really bothers me that he isn't bald, lol. I'm only halfway through the first season so perhaps that will rectify itself in time. Gene Hackman as Lex is a great criminal mastermind, while Kevin Spacey best embodies the insanity of the Luthor character.
That's my take. I apologize for being so long winded!
