The question is actually as old as AN AMERICAN FAMILY, one of the first widely popular reality shows… back when the idea was a novelty. The show ran briefly in the early 70s, but made a big splash. Yet right away, some people were asking if it it was, in fact, reality. If the cameras and production crew altered the reality.
Albert Brooks explored that question in his movie spoof REAL LIFE, which was all actors (including Charles Grodin) pretending to be a real family, and Brooks pretending to be a clueless producer who keeps ruining the experiment by inserting himself into their lives.
