Limitless scene analysis

Bradley coopers character is always in the centre of the frame showing that he is dominant, we can also see that he looks much smarter than what he looked like before he took the drug. 

The lighting has also changed to a much brighter shade to reflect that he is more aware of his surroundings and that he has a more positive attitude. 

The character is now in a more controlled environment, his apartment, which he cleans, this represents that he is finally moving forward and progressing from his boring mundane life.

We can see that Bradley's performance has changed as he is more upright and alert. His makeup and hair have not changed due to the fact that the scenes are close together in sequence.
