Hope this helps someone.
netflix has introduced me to some very interesting, and now part of my favorites collection, movies that I would of otherwise never watched.
Revolver
Ip Man (the first and the sequel)
Just to name a couple.
I havent found anyone or anything that has been able to confirm fact, but I've read some speculate it has to do with their supplier contracts.
