I try to treat every job with the exact same level of respect. When I go into it, it doesn't matter what the budget is or who the lead actor is. You should have the same focus and the same drive, and you should have as much empathy for your character and understanding of them as you would, no matter what.
Prefer the familiar word to the far-fetched. Prefer the concrete word to the abstract. Prefer the single word to the circumlocution. Prefer the short word to the long. Prefer the Saxon word to the Romance.
