The issue is do they watch movie? I know for sure that movies do affect our perspective and even change it towards something we viewed differently in the past but the question now is if those in power there are into movie - it could just be that the reason they are making any of their decision is purely because of what they think of gambling on their own and not because of what they saw in a movie.
As a child the only thing I got from watching gambling movie was that there’s always fight and death there although as I grew up and started gambling I started to see everything differently.
I believe that the power to create a new outlook for gambling lies with the media and introduction of safe gambling environments like rollspace to make people have a different perspective to gambling
