In the new 90210 series, the actors are now playing themselves and their former characters were just TV show characters. This comes in the beginning of the episode, and when I watched it I thought it was a neat take on how to bring together both the world they portrayed and the real world. The connections being shown now, and the aftermath of the 90210 TV show reunion between these actors were the real focus.
Has this style of storytelling been used before? If so, what do you call it?
*One movie I can think of that would probably fit this would be Wes Craven's New Nightmare, where Robert England as Freddy Krueger, and a demon trying to exist as the real Freddy Kruegur, both exist. But that was a little different in that Freddy was really in our world with his powers.
