Other mistake: During the restaurant shoot out between Jr and the bad guys, he takes Sasha's weapon (Kel-Tec P-3AT) and opens fire on the bad guys. The Kel-Tec P-3AT is chambered in .380 and holds 6+1 rounds. During the firefight, Jr fires 9 times. We also see the bottom of a spent casing and it shows .22. (01:12:00 - 01:13:00)
Character mistake: After the shootout at the restaurant, Junior finds one of the perps' cell phone and calls Bennie, exposing her as the one who sent the killers. He even comments in front of Sasha "Got your ass" before telling his dad about it. Later outside the warehouse, Sasha comments "So Bennie is the one who put out of the hit on us at the restaurant." She should already be well aware of that. (01:14:15 - 01:23:20)
Revealing mistake: When Shaft thinks about the address of the drug supplier, he stares at a newspaper clipping on the wall. The clipping is zoomed in close for over 1 second, and it's more than enough to spot the famous words "Lorem ipsum..." at the beginning of the article, revealing the clip to be just a movie prop with the industry standard filler text jibberish. (00:27:10)
Character mistake: Shaft meets Junior for the first time and mocks him with the offer of bubbly water. Junior says "And as for that wedge of lime, it makes it alkaline, so..." It wouldn't, since lime juice is rather acidic. (00:23:10)
Continuity mistake: Young Shaft is meeting his friend at the bar: he has just his solitary drink before him when Karim arrives, but the drinks are now 2 with Sasha's arrival - only for a single shot, though, as just a single glass is afterwards. (00:11:40)
Continuity mistake: Shaft Jr is in an FBI meeting, and the director asks for a volunteer for a mission. Shaft raises his right hand, next shot his left hand is raised. (00:10:05)
Factual error: During the FBI briefing, the coordinates of the mosque supposedly in Harlem are shown on screen long enough to allow you to read them. The coordinates are 34.1234379 -117.177613, which would put the mosque somewhere in California. (00:09:45)
