In my little corner of the world (Yuma, AZ) Ray Kroc is not only known, but memorialized. When Ray owned the San Diego Padres they took Spring Training here in Yuma. Halfway between San Diego and Phoenix. The complex is named after him, and is a community centerpiece. I think every charity in town has a plaque dedicated to him.
Which makes me really want to see the movie. Thanks for a great review!
