The fun thing about doing origin stories is you are introducing the audience to characters.
Hopping around time in a non-linear storytelling fashion (on 'Lost') allows you to bring back characters who are dead and, in some cases, buried. Now that time travel is the story itself, it opens up even more doors. So when an actor reads that they're getting killed off on the show, they're basically, like, 'Okay, but should I still bother to show up next week?'
Some of the things I love the most are when a writer or a visionary takes on sort of an iconic character and then spins it. Like with Frank Miller, Batman was this one thing for basically forty years, and then Frank Miller came along and said he can also be this other thing. And Christopher Nolan came along and said he can also be this other thing. The idea of taking iconic comic book characters or superhero characters or mythic characters and subverting the genre or coming up with a new idea is something that's really interesting to me.
