Missing:
Carne Y Arena (again because it's not actually a movie)
SPECIAL AWARD
To Alejandro G. Iñárritu's CARNE y ARENA virtual reality installation, in recognition of a visionary and powerful experience in storytelling.
I know a lot of juvenile actor awards were given out by the Academy, however, a film is not specified most years, if anyone can convince me of a specific film for a juvenile actor I will add it.
