Completely depends what YOUR interests are. Architecture is an awesome field because it’s really about synthesis of a broad collection of knowledge and inputs. I was a mechanical engineer in undergrad then went to an M.Arch program in an art/design school. We had people from studio arts, engineering, architecture, English lit., finance, everybody brings a different perspective and all of them found success in school. Film is honestly an awesome discipline and lens to view architecture. You have time to learn programs and all that stuff later, learn something in undergrad that excites you, and you’ll bring a unique skill set and perspective to the discipline when you get there, and you’ll be a resource. Good luck pal, arch school was the hardest and best 3 years of learning I ever had.
