Now, when it comes to The Joker, it's hard to do anything to improve on Heath Ledger's legendary performance back in The Dark Knight. Sure, Jared Leto's going to give it his all - but there'll always be a special place in most Bat-Fans hearts for Ledger's iconic portrayal.
And yet, while we may be lacking a performance to match Ledger's, there are a whole lot of other ways to re-invigorate the Clown Prince of Crime - as a whole lot of awesome fan-artists have proven.
Some of what's coming up is strange, but this is The Joker we're talking about, so trust me - that's just part of what makes it awesome...
