Honestly, my character doesn't have much in common with Harry Potter besides the fact that he's an unlikely hero who's thrown into a huge situation.
When I receive a new role, I completely become my character.
For me, being able to be vulnerable is difficult, but it's just something that I feel comfortable doing. I need to fully understand why, the thought-process behind the character and I have to believe it. That comes from a lot of preparation.
It is obvious when an actor has put work into prep and research and understanding their character, and they're making choices, because that's what happens when you take the time - or have the time - to really think about the material, but that only accounts for about 60% of what happens on the day. When you're in the moment, you throw it all away. Well, you don't throw it all away, but it's in you now, and everything is reactionary in that moment and you have to be honest and present and listening.
