Audio problem: After Lara's two Greek partners have their throats slashed, you can hear one of them call out to warn her of Chen Lo's men.
Audio problem: In the scene where Lara and Terry are riding the motorcycles through China, the tires squeal every time they take a corner. How can rubber tires squeal on gravel, dirt, and grass? (00:35:25)
Continuity mistake: When we first see Lara in her silver wetsuit, there is a torch strapped to her left shoulder. When we see her underwater it is missing and when she emerges in the temple it is back again. (00:07:30 - 00:08:40)
Continuity mistake: When Lara seats herself in front of the brown glass base that holds the Orb, you can see three fresh fingerprints. (Lara is on the other side, so the prints weren't made by her.) In the 2,000 year time span since someone last visited, they would have been covered by dust by now.
Factual error: The skyscraper that Lara jumped off is in the Central CBD in Hong Kong, but she got on to the top of the building by catching a lift from a shopping centre in Causeway Bay (another HK suburb).
Continuity mistake: At the end, Lara shoots Terry right in the chest/stomach.However, just seconds later, after he went down, we see Terry laying on the ground...not even bleeding. Not the slightest mark of being shot can be seen on him. (01:40:20)
Deliberate mistake: When Lara and Terry escape the Shay-Ling, they are shown leaving the area and pass a sign that says 'Shanghai - 74 KM.' On a remote mountain passage, coming from a presumably well-secluded encampment. In English. Fat chance. (00:47:45)
Plot hole: When we first see Lara in her wetsuit, she has a back pack attached to her harness, a torch on her left shoulder, some sort of pistol-thing on her thigh, her 5-barrel dart gun by her left buttock and a little pouch in the small of her back. In the temple she takes off the pistol-thing, dart gun and backpack, yet after climbing the statue manages to produce a video camera, safety spectacles and a cutting/welding device from somewhere.
Factual error: When Lara hops on the boat and asks if she can use their satellite dish they continue to watch TV even after she has moved the dish. Anyone with satellite knows how exact the aiming has to be and if the dish gets moved or bumped you get zilch for TV.
Factual error: For the scene in Shanghai, they actually used Hong Kong cars, the Isuzu truck and the Mercedes S-class, as the cars are right-hand-drive, like Hong Kong, while in China cars are left-hand-drive. Also the license plates are not real. The helicopter in the same scene is one that belongs to the Heli-Services in Hong Kong, painted black.
Continuity mistake: Just before Lara skewers the antiquities dealer below the armpits, he's standing a metre or so in front of the crate. Immediately after, he's right up against it. (00:45:00)
Continuity mistake: Lara cuts her arm at the Lunar Temple before she leaves. There is no blood whatsoever until a quick shot shows her pulling her hand away from the cut (it wasn't covering it before while she was swimming) and the cut pouring blood, which immediately disappears as the shark shows up. The blood is never seen again.
Plot hole: When Lara and Reiss (and later Terry) enter the cradle, Pandora's Box is floating on top of the black acid. After Lara kills Terry and returns the box to the acid, the box promptly sinks. Obviously, due to the lethal nature of the acid, the writers needed the box floating on top but there is no "story-line" reason as to why it would sink when returned to where it previously was. (01:37:05 - 01:45:20)
Factual error: Lara's GPS gives her position as 22.15N, 114.10E. This is the position of Hong Kong airport which is over 20 miles from the city center where Lara really is. A rough calculation shows she should be around 114.4E. (00:58:30)
Continuity mistake: As Lara approaches the boat on the jet ski, her knife alternates between being strapped to her left arm and her right. (00:03:45)
Factual error: Luna is the Roman name of the moon goddess. Alexander the Great would have dedicated the temple to Selene, which is the Greek equivalent. (00:04:45)
Factual error: Terry Sheridan is described as a former commander in the Royal Marines. This is a Royal Navy rank, the equivalent Marine rank would be Lt. Colonel.
Continuity mistake: When Lara vaults over to the helicopter, in one shot Terry is kneeling down behind the wall but in the next shot he is standing up looking over the edge. (00:55:00)
Continuity mistake: When in Hong Kong, flying off the building under construction next to Times Square, they pass/ fly by Chater Garden and the Lippo Centre. Neither of those, or the building under construction, are near the lab they're escaping from.
Continuity mistake: When Lara is kissing Larry she turns around and lies on top of him with her pony tail dangling to the left. A shot later it's on the right side. (01:12:55)
Answer: The pressure in the temple would be the same as that of the water just before Lara entered the temple. So no she would not need to decompress before entering at the temple as it was open to the sea, but she would have surely suffered the bends on the rapid accent to the surface.
