There is a rather interesting science fiction movie, called "The Thirteenth Floor", that explores this concept, in fact if I remember correctly it talks about nested simulated worlds.
This makes perfect sense to me, if the theory that we are living in a simulated universe is correct, the exact same logic would apply to the beings that are running the programs to simulate us and so on, ad infinitum.
