Filmmaking is a rewarding area, but anyway, my future movie studio is now going to be a multimedia studio, after realizing that such business won't work right. This post explains several reasons why I'm unlikely to, don't need to, and shouldn't open a movie studio.
Theatrical films cost dozens of millions of dollars in development, pre-production, production, post-production, distribution and marketing. This would need huge investment in such productions and salaries, and this is unlikely that it will turn into a profit.
Most movie studios and film production firms apply for tax incentives, in which you don't receive funding on your own, but from a local film office.
Theatrical film is a pretty saturated sector, with lots of generic horrors, dramas and comedies, and even Hollywoodian superheros flooding the market. So, this would be more difficult for a well-produced production in that area to reach the audience.
Most movie-only studios are located in Los Angeles, NYC, New Orleans, Atlanta and Albuquerque metro areas, making units rarer outside such hubs.
Two words: talent shortage. Depending on where your movie studio is located in, local talent in the area is harder to attract, with its professionals moving to obvious hubs. This would need me to invest heavily in training, no exceptions.
The Midwest and the Northeast have a history of unpopular filmmaking, with its founders born in said places of the both regions moving out. When you live in the Midwest or the Northeast, you rarely see the most brilliant scene: production happening during the shooting dates.
In addition, acquiring and relocating such studios will never, ever work, as you will always face resistance all day. If you do so, this will be no better than all of the resistances of those huge company buyouts and mergers.
