Ray Kroc built an empire — and he took it from the founders. Richard and Maurice McDonald started the ubiquitous fast-food restaurant in 1948. They were never interested in expanding, until Ray Kroc joined them in 1955. Kroc took the business from a handful of locations and built it into the behemoth we know today. Michael Keaton stars as Ray in The Founder, in theaters January 20, 2017.
