As I am changing careers, from BBA to film-making, should I get a Masters in the new field or another Bachelors?

I will be graduating this year from a course of BBA (Computer Applications). I do not want to pursue this field as my talents are best utilized in another career, film-making (direction, editing, scriptwriting). I want to pursue this field abroad, and I cannot decide whether to get a B.A. or M.A.
