Tom Hardy as Killer Croc in BATMAN 3?

Last week comic book writer Mark Millar said in a tweet that he knows who the villain(s) will be in Christopher Nolan's Batman 3. He went on to say that,

One of the villains is from my favourite childhood run on the character. Again, very unexpected. 

He didn't reveal who these villains were at the time. It was revealed today that Tom Hardy was cast as a lead character in Batman 3, I assumed he would play a villain. Not long after the news broke Millar tweeted the following,

Tom Hardy as Killer Croc? I like the sound of that. PS Superior #1 out today, but sold out in 4 hours. Thank you, fellow gingers. 

I would love to see Hardy take on the role of Killer Croc, and the character would make a great villain in Batman 3! As of right now this is a big rumor. It all depends on how you feel about Millar and the things that he say's. The guy likes to talk. But there's a chance he might know something we don't know.

If this turns out to be true, what do you think about Hardy taking on the role of Killer Croc?

In Croc's initial string of appearances — a Detective Comics story arc that culminated in Jason Todd adopting the mantle of Robin — he was depicted as an unnamed, shadowy figure in a trenchcoat. A ruthless criminal who wants to become the crime kingpin of Gotham City, Croc works behind the scenes using methods like sniping to eliminate his criminal competitors. He briefly unites a small army of Batman villains under his leadership. When Batman finally confronts his mysterious foe, the villain is revealed to have a massive physique and reptilian appearance. It is then revealed that his real name is Waylon Jones, born with a form of atavism that imparted him with reptilian traits. His parents grew to loathe their child's hideous appearance and brutal behavior. While still an adolescent, his father abandoned him in the wilderness. Croc survived, becoming a career criminal.
