Reality vs Tv illusion

Truman faces a false reality, his dearest friends and family, helps build the illusion of a utopia.

Truman believes everything he witnesses is real he cannot tell the difference between reality and illusion, he thinks he's free and is able to leave anytime he wants.

His whole world is superficial and he doesn't notice until it all falls apart.

In the final scene you see him destroy the illusions that were once created for him, we know the illusion is over
when he says "in case I don't see you good afternoon, good evening and good night".

Truman lives in a simulated reality.
