Aim to just get into acting - forget the 'big' thing. Only a tiny percentage of actors ever get a good role in anything, and that's largely through good luck. To become an actor you're going to need huge natural talent, many years of high-level training (the average is 7 years) and loads of stage experience.
But only try if you simply love to act, no matter if it's paid or not, and with no ideas of 'fame and fortune'. Real actors don't care about those things - they just want to act.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
