So who's made it into the Top 5 best performances? Robert Downey JR? Michael Keaton? George Reeves?
Hmmm... only one way to find out. Read on!
If his first appearance as Marvel's most iconic mutant in X-Men (2000) wasn't enough to convince you that he was the real life embodiment of comic-book character Wolverine then his performance in X2: X-Men United (2003) surely did the trick. As the mutant with the worst memory in the Marvel Universe Jackman portrayed Wolverine with just the right amount of sensitivity to match the character's animalistic nature.
Jackman's later performances in both X-Men: The Last Stand (2006) and X-Men Origins: Wolverine (2009) were genuine highlights in those lacklustre X-entries and he achieved bonus points for his cameo in X-Men: First Class (2011).
There's a reason that studio execs have struggled to get a new Wonder Woman project off the ground and that reason is Lynda Carter!
As TV's star-spangled superheroine Carter dazzled audiences for three seasons of the 1970s Wonder Woman TV show and even when the show started displaying signs of fatigue Carter's performance still kept the character going strong!
Confident, iconic, yet identifiable, Carter's Wonder Woman really was wonderful and her performance has yet to be topped. Oh and don't even get me started on that spin transformation that she used to do each week that turned her from geeky Diana Prince into DC's Amazing Amazon!
Lynda Carter's transformation into Wonder Woman was pretty cool, but nothing compared to the transformation that turned Bill Bixby's David Banner into the Green Goliath known as the Hulk. With just one flash of his pale green eyes audiences knew that Banner was about to be taken over by his monstrous personality and soon the stuff of legend was born.
Bixby's performance as the doctor trapped by his own demons gripped audiences for five seasons and was the driving force behind the show's success.
Technically Bixby may not have played the Hulk, but he's a big part of why the Incredible Hulk is still popular today.
Kevin Conroy is Batman. This is a fact.
Adam West, Christian Bale and Michael Keaton may have played 'your' on screen Dark Knight, but it's Conroy who is the real Caped Crusader.
His performance as Bruce Wayne/Batman in Batman: The Animated Series won him a worldwide fan base due his serious take on the material and it's the reason that he continued to provide voiceover duties for the character on Justice League/JLU, Batman Beyond, Arkham Asylum and numerous other Bat-related projects.
As if there could be any other actor/actress at the top spot.
Many actors have worn the famous red and blue suit to play Superman, but it's Reeve that wore it to become Superman! His goofy take on Clark Kent was the perfect contrast to his determined performance as the Man of Steel and it has helped to define the character for generations to come.
Reeve's Superman was also the best thing in the piss poor Superman sequels Superman III (1983) and Superman IV: The Quest for Peace (1987) and his popularity is one of the reasons as to why the series has struggled to achieve the same success ever since.
