There also is another thought process going on where it's like, yes, [my last movie] could be original. On the other hand, maybe that could show a different career I could've had. Whereas maybe [Once Upon a Time in Hollywood] is my last original -- I'm not saying this is the case -- but maybe this is my last original, and Star Trek or any other thing, a book or something like this, is the career I could have had if I wasn't just writing everything all the time. Writing always originals. Maybe I could have had a different career if I looked for other people's scripts, or if I wanted to find a book to be inspired by, and do an adaptation of. That would've been a different career. And maybe that could be fun to explore on the 10th [movie]. I don't know. I mean, I'm making all this up as I go along, but those are two different ways I could look at it.
