Without the exact context from the film, I can only speak generally about this expression. When you are "above" something, it means that your values, intelligence, experience, or point of view allows you to look at the situation from a more enlightened perspective, or allows you to "see the big picture." You are above it. Conversely, if for example, someone insults you, you may want to insult them in return. But you would then "lower yourself" to their level. Rather you choose to "rise above" the situation and respond more appropriately. You are above it all. Hope this is helpful.

When we say you're above that, it means that to situation is beneath you. This means basically that you do not concern yourself with the petty situation that is given. "That person just made jokes about my mother!" - "Don't worry, you're above caring about other peoples' jokes."

It means you're too "high" (in intelligence, society, etc.) to participate in a situation or to be affected or bothered by the situation. For instance: Me: I'm broke. Friend: You could beg your parents for some money. Me: I'm above that. OR: Sister: I'm going to that crazy rock concert. Me: You're above all that. Hope this helps!
