Other mistake: The janitor, Howard, stops Dr. Stone to talk to him about the loss of his son. Look at his badge; the person on it sports a beard and sideburns and a hat, and it's "Jensen" plus initial. Later on the same janitor hears a noise inside the lab and you can see the badge picture is different and it lists the full first and last name. The first scene was a Whedon reshoot, so probably after weeks they didn't have the original prop and made another one. (00:18:55 - 00:21:15)
Other mistake: When Ruby Rose is introduced, the Italian localization does not understand the reference to the game "Call of Duty", and thus just translates the expression literally. Italians play "Call of Duty", not "Dovere." (00:33:10)
Other mistake: When Hennessy shoots McGrath in the leg (twice), there is no blood. McGrath grabs his thigh, then writes the names of the bombers, and there's still no blood anywhere.
Other mistake: Towards the end of the movie when Spencer is riding the motorcycle to the top of the jaguar statue, he throws the grappling hook and swings on the rope. When Martha hands him the jewel as she falls, the rope he was swinging on disappears.
Other mistake: The film takes place in 2020. However Lin's fake passport expired in 2015.
Other mistake: They make it clear to us that the portals are one-way gates (from origination to destination). However, the last portal is two-way.
Other mistake: After Ray patches up his shoulder from being shot, he heads out answering a call from Jacob. As he's talking he gets hit in the neck by a sleep dart and his phone is shown. The screen still shows an incoming call, rather than one in progress. (00:38:20)
