Bachelor of Mass Media (BMM) would open various new options before a student of the stream. Students of BMM can further study mass media, radio journalism, print journalism, television journalism, photography (both steel and movie), editing, film direction, etc. It is a very useful course which hones the technical competence of such students who wants to pursue careers in various branches of mass media.
If your son has the inclination to go for film direction, this course would be very useful for him. However, I feel that only BMM would not be sufficient, he will have to go for study at Masters level with optional paper in film direction. You must make serious attempt to get him admitted in a reputed institute in this field. Please avoid the little-known institutes mushrooming in every city or town of India.
