I think we've all been kind of... everyone's been hurt, everyone's felt loss, everyone has exultation, everyone has a need to be loved, or to have lost love, so when you play a character, you're pulling out those little threads and turning them up a bit.
Each role, I feel like takes you on a different journey based on who that character is.
When you're trying to do character work that's different from what people expect from you, you're sort of in territory that is uncharted, and you don't know how it's playing all the time.
