Production Focus and Challenges

I would say one of the major challenges was working on the final sequence and having to see everything about to go down! As a fan, it sort of sucked some pizazz out of the experience.

That said, the speed of production was challenging. With the rapid timeline and the “relative” smaller lookdev team meant being intelligent about how the environment work was split.
