I highly recommend this film about the true story of the founding of McDonald's Corporation. It's about an ambitious malt shake mixer salesman, Ray Kroc (Michael Keaton) and his chance encounter with Mac and Dick McDonald in 1954.
Mac and Dick have a highly successful hamburger stand in San Bernardino, CA. These two brothers have developed a speedy assembly line for producing hamburgers at a rate of 30 seconds from beginning to end. They changed the idea of a food stand or drive-in and came up with a cost-efficient model that is highly effective in reducing overhead costs. Ray Kroc sees the potential of this and goes into partnership with franchising the company, McDonald's.
