So not a real movie.

I actually think this kind of thing would work for a studio comedy now and again. Or once. Play to the reality of the situation rather than the wish-fulfillment fantasy. Satirize the genre without buying into the tropes of the genre for the second half of the film—a la “The Other Guys” and “21 Jump Street.” But that would take risk and imagination. Artists want to make the new; businessmen want to make what's made money.
