Random GM thought:
-Aside from France, Germany, the UK, USA, and Italy, most nations have a very minor film scene, getting most of your films imported from one of the Big 5. This means you have few directors, screenwriters, people who know how to do the lighting, ect. You can absolutely invest in this of course, but just understand it will take a few years for you to build it up to the level of the bigger players. The Han are doing well with investment in that sector too.
One other thing you should think of though is also potentially subsidizing theaters so your films can be seen.
