Continuity mistake: In the opening scene where Alex's partner is in the car with the bad guy, when she pulls her gun and he hits the brakes sending her into the dash she is not wearing a seat belt. Immediately after, when the car goes over the side of the dam, the shot looking down on her shows her with a seatbelt on, the reason she didn't fly from the vehicle. (00:04:10)
Suggested correction: She's wearing a seat belt at 00:03:50 when he's trying to get some top from her. He's pulling on her head and that's when he finds the Bug in her ear. And you can see she's wearing a seat from 3 mins to the time she's hanging from the bridge in the car. 00:03:50-00:04:11.
Suggested correction: I just rewatched - she is wearing her seatbelt when he slams on the brakes, and she hits her head.
Continuity mistake: After Freeman and the Main Detective girl are at the beach looking at the body of the man who was shot in the water trying to save the little girl, Freeman says "let's go back to the city". On their way back in the car, of the three times the camera is on him, he only has his seat belt on twice. (00:50:00 - 00:51:00)
Continuity mistake: At the beginning of the film when Freeman's partner shoots the guy in the Corvette and the car starts flipping, the right front tyre is shown coming off the car and tumbles in the air several times, but when the car is finally getting tangled in the guard rails, it shows the car with still 4 tyres on. (00:04:15)
Continuity mistake: During the "running game" segment, Cross gets a cell phone that uses an earpiece and is told to keep it (for further instructions). When he gets to the subway loading platform, he gets another call, but he is not wearing the earpiece while he listens to the new instructions. Soon after that he is shown wearing the earpiece again while he listens.
Suggested correction: You probably haven't focused on Morgan Freeman's ear. The cord of the earphones are hard to see in that sequence and you may be led to think the whole apparatus is gone, but if you just look at his ear you'll see that from the entrance to the escalator to the platform to the train, in every part of the conclusion of the 'running game' happening in the station, Alex Cross is wearing the phone earpiece.
Trivia: After Morgan Freeman shoots the guy with the shotgun, the next scene is outside with the news crew and you will see Morgan Freeman walk by the camera dressed up with dreadlocks and cap and keeps looking at the camera. It's Morgan Freeman playing an extra.
Suggested correction: I agree, it's definitely not Morgan Freeman. If you're talking about the guy in the red knit cap and what looks like a red sweater vest, he doesn't have a mustache and his nose is completely different from Freeman's nose looks like in profile. Without any confirmation from someone from the film (such as a director's commentary) or further evidence, this isn't valid trivia.
Suggested correction: Wow, I find pretty extraordinary that this cameo is not mentioned anywhere else. The guy does look like Morgan Freeman (I am adding a screenshot to the entry), and is not seen anywhere else in the scene, nor Freeman is in the wide shot, so I can't say the entry is false, I just find it quite strange since usually this sort of humorous bit roles get mentioned a lot. Kudos for noticing.
That is not Morgan Freeman.
