Despite the notion that actors are snooty Hollywood types, many actors form theatres for their communities and draw on local talent and craftsmen embody acting with their own community spirit.
That's interesting, so what's the rational behind the info?
You can think of Hollywood as a big comminity theatre itself and its community being culturally significant, but oftentimes it can blind them to certain communities own style, history, and legends.  Local community theatres can fill in that gap.
So the topic sentence is ?
Community theaters!  They help represent the local culture and flavor without having to be pre-screened by powerful Hollywood producers!
