Agreed, and this is the real Superman.
Christopher Reeve isn't the "real" Superman to me, but your post got me thinking about the live-action actors that personified the DC comic book characters the fullest in my opinion. Out of all of the live-action actors, George Reeves is the "real" Superman to me, and Michael Keaton is the "real" Batman to me. George Reeves captured Superman's charisma, confidence, aggressiveness, maturity, dedication to a never-ending battle for truth, justice and the American way. George Reeves captured both Superman's rugged and distinguished sides, authoritative fatherly figure, yet gentlemanly, and polite, and Clark Kent's coy, believably mild-mannered persona without acting bumbling and inept (Christopher Reeve's Kent). Christopher Reeve's Superman was none-aggressive, less enthusiastic and willing to give up his life as Superman to be with Lois Lane. Jason Kemp in Rear Window was Christopher Reeve’s best performance in my opinion. Kirk Alyn's Clark Kent was bumbling and his Superman was goofy, prancing and skipping around like a flea. Dean Cain lacked the mature presence and gravitas of Superman. Brandon Routh's Superman was a non-violent, sensitive, emasculated metrosexual, deadbeat dad, jealous peeping tom, soft spoken baby-faced pretty boy with brown hair wearing a spandex costume with low-riding short-shorts. Henry Cavill's Clark Kent is reportedly lonely, angst-ridden, not wanting to be Superman, and reluctantly grappling with whether or not he should become Superman.
Michael Keaton captured Batman's innate grimness, maturity, self-reliance, capability as a detective, inventor, mechanic, etc., displaying controlled calculating anger, intimidation, and Bruce Wayne's playboy persona and philanthropy without acting like a sterile saint (Adam West's Wayne, as is West's Batman) or a pompous jerk (Christian Bale's Wayne). Lewis Wilson lacked the distinction between Bruce Wayne and Batman's voices that Michael Keaton utilized so well. Over-weight Robert Lowery lacked Batman's fit figure, mobility and looked laughably ridiculous in costume. Val Kilmer's Bruce Wayne lacked the black hair and lacked the confidence of Bruce Wayne, as he displayed an uncomfortablity, awkwardness and was unsure of himself, and Kilmer's Batman spouted dialogue that is ridiculously out of character for Batman, "Chicks dig the car," "I'll get drive thru," etc. And getting over has parents death and deciding to quit being Batman to live as Bruce Wayne misses the driving force of the Batman character which is that he's avenging his parents by dedicated his life to warring on crime, and unlike Peter Parker, there is no looking to get out of it. As Keaton's Batman said in Batman, "This is something I have to do. This is how it is. It's not a perfect world." Also, Kilmer's Bruce Wayne says "I killed them", in Batman Forever, has a Uncle Ben guilt complex over his parents death. And Kilmer's Batman complains like a worried girlfriend after Robin just saved his life, "You could have gotten yourself killed!" George Clooney's Batman lacks any menace and Clooney's Bruce Wayne acts and speaks identical to his Batman, detached and bemused with a tendency to smile at somber moments. Christian Bale's Batman lacks Batman's detective skills, strategy skills, etc., while Cain's Alfred, Freeman's Lucius and Oldman's Gordon do a lot of the thinking for him. Patrick Bateman in American Psycho was Christian Bale's best performance in my opinion.
Lynda Carter is the "real" Wonder Woman to me. Lynda Carter captured Wonder Woman's strength, independence, security, self-reliance, nobility and upbeat personality. Lynda Carter captured Wonder Woman as the strong, noble, independent and secure female hero the character was created to be. She was a feminist icon and female role model. Adrianne Palicki's Wonder Woman is heartbroken, sad, mopey, self-pitying, she cries herself to sleep over her ex-boyfriend whom she has been broken up with for four years, which diminishes the character. Adrianne Palicki's Wonder Woman also throws a pipe through someone's throat and stabs him to a door and she tortures a guy for information while breaking his arm, while the lasso of truth is right there at her side. That brutality is completely contradictory to Wonder Woman's mission to bring the Amazon ideals of love and peace to the world of men. Adrianne Palicki's Wonder Woman is also a mega-billionaire, the chairman of Themyscira Industries licensing her image to dolls to make cash for herself. Too often in films and television we see women being portrayed as overly emotional drama-queens, over-reacting divas, breaking down and needing a strong, level-headed independent and secure man to save them. Wonder Woman was created to be a rebuke of that stereotype of women as weak and overly emotional.
Ryan Reynolds captured the humanity of Hal Jordan, the light-hearted humor, the ladies man aspect of Hal, Hal’s human foibles. Howard Murphy‘s portrayal of Hal Jordan in Legends of the Superheroes was completely campy and ridiculous.
Tom Tyler is the "real" Captain Marvel to me. Tom Tyler captured the child-like nature of Captain Marvel with the smile, the sense of having fun during his adventures. Jackson Bostwick and John Davey lacked that child-like quality of Captain Marvel that makes Captain Marvel so unique amongst superheroes.
Michelle Pfeiffer is the "real" Catwoman to me. Michelle Pfeiffer captured Catwoman's playful flirtation toward Batman, her love-hate relationship with Batman over her attraction to him and the conflict of her criminal activities, and the ambiguity of Catwoman being a villain but not being truly evil. Halle Berry's Catwoman isn't even Selina Kyle. Julie Newmar, Lee Meriwether and Eartha Kitt's Catwoman was a generic villainess trying to kill Batman and Robin in various death traps. Anne Hathaway’s Catwoman seems to hate Batman/Bruce Wayne for being rich, and hates rich people in general, as her dialogue suggests in the trailer.
Jack Nicholson is the "real" Joker to me. Jack Nicholson captured the Joker's vanity, theatrically, sense of style, chemistry ability. Killing people in stylish and theatrical ways with permanent smiles on their faces through his Joker venom (Smilex). Jack Nicholson captured Joker's style of arbitrary chaos, anarchist schemes with stylish theatricality, and wanting ridiculously vain things like his face on the one dollar bill (which is similar to wanting to copyright fish that look like his face in the comics (Detective Comics #475 (1977) "The Laughing Fish")). Cesar Romero's Joker was a goofy crook with a predilection for slapstick gags and Heath Ledger's Joker lacked the Joker's vanity, theatrically, sense of style, chemistry ability, he was just an anarchist killer in sloppy clown make up, not about killing with style.
Danny DeVito is the "real" Penguin to me. Danny DeVito captured the Penguin's murderous nature, his anger at being an outcast that was rejected by society, his dark humor, even his bird obsession, also his conning personality pretending to be high class and respectable as a front for his villainous activities. Burgess Meredith's Penguin was just a silly crook.
Aaron Eckhart captured the tragedy of Two-Face, the torn, internal struggle of the duality. Tommy Lee Jones' Two-Face lacked all of that and was just a silly giggling buffoon.
