Best Modern Actor for the Role of Nero

Taking into account all that I've learned about Nero, I would say that Tom Hiddleston would be the best candidate for the role. Given that Nero was not a warrior, he probably had a slim stature, like the one that Hiddleston posesses. And when looking at the variety of roles that Hiddleston has played, having him be a mix of a playboy, a villian, and a likeable character would be well within the realm of what he can do.
