There is only a six year age difference between Richard Roundtree (Shaft I) and Samuel L. Jackson (Shaft II). This is humorously acknowledged in the film when Roundtree rhetorically asks, "How come you look twenty years older than my gray ass?"
At one point in the film Samuel L. Jackson tells his son that he got a real Super Bowl ring from L.T., referring to former NFL player Lawrence Taylor. This is also likely a reference to the previous Shaft (2000) in which Taylor appeared, although he was not playing himself but an actual character in the film.
This film will be released on Netflix streaming services internationally.
At the time of the film's release, the main three actors ages are as follows: Roundtree 76, Jackson 70, and Usher 27.
