Well, a few things came to mind about things in movies that remain a mystery. Or just plain and simple never get explained. For instance, how would the movie "Last Action Hero" actually of went as, Jack Slater 4? That one always kinda boggled me about how would the movie actually of went had Danny never popped into it? Would it in turn actually been a kick ass movie? hahaha! I could list about a dozen things at least about Back to the Future as well. Anyone else think of a movie that had something that just wasn't explained?
