Will it be Loki or will it be Bane. From Nolan's previous casting decisions with the casting director, we have Liam and Heath live up to the part of the villain that is the scourge of Gotham.
I believe a lot of fans and haters of Batman don't know the history of an actor such as Tom Hardy. Hardy has the ability to transform into any acting role, the diabolical serial killer is a role that fits him well and he has executed a role such as this previously.
If we look at a comparison, Hardy has acted in films such as Bronson, the British crime series The Take, recently the Warrior and in the future Mad Max. Hiddleston is also a talented actor nonetheless but in comparison is not remotely close to being the true definition of a CBM villain.
I believe this summer will see the emergence of another superstar actor in Tom Hardy, as his stock will rise exponentially because his depiction of evil is currently imo second to none.
