You become a filmmaker the day you feel this special feeling - love for the Cinema and all its roles. A guy working in an office who suddenly feels the excitement to buy a camera and shoot his kids on his free time is already a Filmmaker. Anyone who makes something with a camera is a filmmaker. There are people who are happy just dreaming of it, while others (like Frank Capra said) are brave enough to make movies.
