Visible crew/equipment: In the last scene when Riley Poole is walking to his home and spots his Ferrari that was repossessed, when the camera tracking shot stops, in the reflection on the side of the car you can see the camera and the camera track reflected in the door of the Ferrari.
Visible crew/equipment: At the last scene when Riley Poole gets in his Ferrari, you can see the camera man in the reflection by the head rest of the seat. You can see a black dot moving. That's the camera man's head.
Answer: Gates' name was added by Wilkinson to get Ben to do all the work in finding the treasure (as that would prove Thomas's innocence).

I disagree, Gate's name was always on the page. Presumably the investigation of the page would have revealed that it was a recent addition not a contemporary part of the text if this were not the case. Perhaps a simpler explanation is just that the conspirators needed to consult gates due to his deciphering skills, hence his name on the page, which explains the name "mastermind" as well.
Thomas Gates was on the page listed as "Artifex" which just means a practitioner of a craft. Mitch tries to say it's a "mastermind" but that's not 100% true, it could be but also just an expert at something. The museum curator who says, "we'll have this authenticated" was paid off by Mitch, so Mitch could very well have added the name and the curator lied.
Mitch says in the movie that adding Thomas's name to the page was the only thing he could think of to get Ben "in on the hunt." He says it at the end of the movie when he is apologizing for smearing Ben's "great great granddaddy's" good name.
Why does finding the treasure prove Thomas Gates' innocence anyway?
