Over the years, cinema has graced us with countless fascinating personalities with even more fascinating origins. For some characters, however, much of their allure stems from the fact that they have remained an enigma to us, mysterious characters whose pasts WE DEMAND TO LEARN MORE ABOUT. With many of them, we were either given their 'version' of their past or simply no backstory at all. Either way, we're left with questions. Which of these mysterious characters portrayed in film, and their surely fascinating pasts, would you be eager to learn more about? (Please note: In order to be eligible for this list, these characters must have a past, whether it being their childhood or background, that hasn't truly been explained in the films they have featured in and thus remain a general mystery to us.)
