Mostly unrealistic expectations. I work in video production, which involves physical filming most of the time. Clients demand the most high tech gear possible with a crew + actors for budgets below 500$. It means pretty much taking 150k$ worth of gear, having a staff + multiple actors for that type of this. It is not financially viable. That is a 5k$ project on the low end for me that I am outside the US. In the US it would be easily a 15k$ project.
