I watched a fun little documentary on the PBS channel (Roku) last night and I learned a few different things. The movie is called Cosplay: Crafting a Secret Identity. You can watch it in full on the PBS site here.
I had no idea that there were so many, working in and around cosplay, make a living off of it. I knew about major costume companies, but honestly I was impressed with the level of grassroots efforts that branched into full fledged businesses.
It's a fun little watch and will only set you back about an hour of your day.
BRING ON THE COSPLAY GIFS!!
