Bubba Lewis, who portrays an adolescent Bobby Jones, is a low handicap player himself. Also a talented actor and singer, Lewis hits the links whenever he can.
The golf courses supposed to be Oakmont and Merion have abundant coniferous trees - not at all a characteristic of either course. And the greens, tees and fairways are cut to today's short lengths and "striped" by modern-style mowers. The equipment of Bobby Jones's era was incapable of doing this. Green speeds in the movie are much too quick - in the 1920s and 1930s, they were about one-quarter of today's speeds.
Prior to Jones' first major win at Inwood NY, there is a scene where O.B. Keeler reads the well-wishing telegram from Grandfather Jones and tells Bobby Jones he is the best golfer in the world. Keeler upon departing grasps and taps Jones' right shoulder with his left hand. In the next immediate shot, you can see Keeler tapping Jones on the same shoulder with his right hand as Keeler pivots.
During Bob Jones's first US Amateur (which was in 1916), when in his room with his playing companion it is mentioned that the tournament contains some NCAA past champions. The NCAA did not exist until 1921, and golf was not part of the NCAA at that time.
