Tom Hardy being cast as Bane has given me the idea of this thread.
Before Nolan announced Bane as one of the main villians of Dark Knight Rises, Bane seemed to be a villian that wasn't very well regarded by Batman fans. Honestly, I never *really* thought Bane was lame, but it seemed like he was a character created just to carry out the shock value of breaking Batman's back, and after that, he was very much oversaturated to the point of fatigue then just drifted off into obscurity only to be remembered as the character who paralyzed Batman.
Once it was announced that Hardy was cast as Bane, the news immedately became the most interesting thing about DKR for me(and still is). This is all due entirely to Hardy in Bronson. That was such a manic, captivating, and un-nevering insane performance and if he's just half -JUST HALF- as crazy as Bane as he was in Bronson, I think we're in for something special. I predict that he's not going to be as feral, but both Hardy characters are actually very similar in the fact that they've both spent most of their lives within prison than they have in the outside world. It's very inspired casting, and has a the potential to be just as memorable as Ledger's Joker.
So all that got me thinking: has this ever happened before? The only example I can think of, and I think I'm in the minority on this, is Topher Grace as Eddie Brock/Venom. Spider-Man 3 certainly is a mess, but I think the Brock storyline isn't a reason why(well, until he's full blown Venom. Then it does get a little crappy but not because of Grace, though). In fact, Grace's Brock was a refreshing change of pace; ironic given how Raimi was forced to shoehorn the character by Arad. The approach to make him more doppleganger in physical apperance, and making Brock a sort of Stephen Glass type person was a nice way to link his origin with association to Peter Parker. While the "tying with association to Parker" approach to build Venom's origin wasn't very refreshing in Raimi's canon, the lack of paternal subtext certainly was.
Going back to Grace being an interesting choice for the character- I always thought he would have made a better Spider-Man, and was my personal choice when it was announced that Raimi was set to direct the franchise.
Anyway, I hope anyone who reads this can think of other examples. Natrually, the majority of this inventory will probably be mostly comic book characters since they have the biggest obstacle of deaing with preconcieved notions; but I can't think of any examples off hand that are non-comic that fit except my fan-casting of Bill Hader as Stephen King if Howard and Goldsman decide to go that meta route for their Dark Tower project.
Also, feel free to fanwank possibilities of what you consider a lame character that would be a great role for an actor/actress. I have a couple, but I'm going to save them for later.
