I can tell you for sure: people who are at their peak right now will not sustain that. You can't. It's against the law of nature.
The imagination is part of the arsenal that actors draw from.
When everyone has high expectation for you, it can attack your insecurities.
The only thing that we as actors really can control is to be able to say 'yes' or 'no' to the material.
Mixing humor and politics is something that works.
That's the reason you want to become a star as an actor, to be able to have more control of your destiny.
