Character mistake: In the meeting in 1984 when Jason Bateman first appears they have players on the whiteboard in the background. They have "Hakeem Olajuwon." He didn't put the H back in his name until 1991. So it should have been "Akeem Olajuwon." (00:08:40)
Other mistake: When driving to the Jordan's home in Wilmington, Sonny reads a highway map when he's driving the side streets.
Factual error: When driving to meet the Jordans you can see a white car in the distance on the right that is from the 21st century. (04:01:00 - 04:04:00)
