While everyone can relate to Breaking Bad's Walter White in some senses – the want to provide, the feeling of inadequacy and helplessness – there are some sides of his character that most of us won’t empathise with, namely the drug manufacturing, murdering and blackmail.

And it’s that middle one – the murdering – that came to Cranston, who has won awards for his portrayal of White in Breaking Bad. The actor has admitted to phoning the police on himself once for plotting to murder his own girlfriend in his head.

"I had one girlfriend I wanted to kill," he explained to GQ magazine (found here). "And I envisioned myself killing her. It was so clear. My apartment had a brick wall on one side, and I envisioned opening the door, grabbing her by the hair, dragging her inside, and shoving her head into that brick wall until brain matter was dripping down the sides of it. Then I shuddered and realized how clearly I saw that happening. And I called the police because I was so afraid. I was temporarily insane—capable of doing tremendous damage to her and to myself."

This scary revelation makes sense when you view it in the context of Cranston’s actions. Like Walter White, Cranston felt anger, but unlike White, Cranston found a way to control it – in his case, calling the authorities to stop himself from doing something awful. But this comes through in the hit series Breaking Bad, and is a perfect example of channelling anger for good; something the late great James Gandolfini managed to do.
