This is a Predestination Paradox and there is a solution.

The answer, I believe, is that we are seeing in the movie - at minimum - is the third timeline.


The future beings interfere in these oblique ways because of causality, the wormhole is by Saturn because it's far enough away that it won't substantially change the course of events that eventually allowed humanity (or their robot leftovers) to create the wormhole in the first place. They use Cooper to solve Plan A because it doesn't interfere with Brand's implementation of Plan B. Anything they try has to be out of the way - to not erase the chain of events that led to the creation of the first wormhole in the first place.



The Interstellar IMAX Print is the largest ever made [as of 2014]. It contained no trailers because of it's massive size.
