Corrected entry: Lara gets the first piece and is out of the jungle. At this point, if she has a brain, she should destroy the one piece she has, and the whole story is finished. (Remember, the idea and offer to use the triangle to bring her father back comes much later in the movie).
Corrected entry: Why did her father hide the letter about the triangle in a valuable book, then entrust a crytpic clue letter to solicitors to be delivered on a certain date? He had no way to be sure the book would still be in the house after 16 years. It could have been sold or given away, or destroyed in a fire. It would have been safer to entrust his letter to Lara to the solicitors directly.
Corrected entry: Lara is somehow able to drag Simon (the robot), which we can assume weighs hundreds, if not a thousand pounds or more, with relative ease in the beginning. This comes from the logic that he is all electronics and metal, which weigh quite a bit.
Corrected entry: When Lara is in the Siberian village, and is talking to a little girl in Russian, the girl says "You'll risk it all for a chance to see him again." Lara: "Who?" Girl:"Your father." However, the girl said the last phrase "Tvoi Otetz" in Russian, when she should have said "Tvoevo Ottza." It's a big mistake in the Russian language. Not to mention an awful pronunciation for a native speaker.
Corrected entry: Early in the movie where they show Lara as a kid, the kid has brown eyes while the adult Lara has blue/grey eyes.
Corrected entry: Lara breaks into a secret room unknown to her when she hears the clock begin ticking. However on breaking into this room she knows exactly where to reach in order to flick the light switch on.
Corrected entry: In the scene where Lara changes the direction of the knife, it is seen moving very slowly through the air in a straight line, point first. Knives rotate around their centre of gravity when thrown.
Corrected entry: In the garage scene, when Lara does the donut on the motorcycle, she does not use the hand brake to keep the front wheel from rolling. That trick is impossible without the front brake being applied.
Corrected entry: When the history of the two parts of the triangle is being told by Lara's father, he said that the people of light broke the triangle in two pieces and hid each bit on opposites sides of the world. (Indeed, you see a cut scene of two horsemen going in opposite directions). Yet the second part is in the ruins of the ancient city of the people of light - quite an obvious place to start looking for it.
Corrected entry: Towards the end, time is frozen with a thrown knife in midair. Lara turns the knife around, then she lets time go to normal speed. The knife changes direction, whereas it should have kept going in the same direction, just butt-end first.
Corrected entry: After Lara sees her father and returns to the pre-present to change the knife's direction, shouldn't there be two Laras since she's the future Lara and the 5 minutes before Lara was standing right beside Alex?
Corrected entry: Lara tries to cook her meal, which is in a metallic tray, in a microwave. You are not supposed to put anything metallic in a microwave. Even though her food exploded, the metallic tray had no effect in the microwave when in reality, there should have been fireworks in the microwave as soon as she turned it on.
Corrected entry: When the UPS man arrives the morning after the gunfight in Lara's house, he must have built-in springs in his shoes. There is not enough time for him to switch the engine off and get out of the van, before he appears in the shot.
Corrected entry: The next day after the battle between Lara and all the troops after her clock takes place. The UPS man arrives, he steps through the open front doors in to Lara's mansion, then it cuts to his feet, when it cuts back to him, the doors he just came through are closed.
Corrected entry: A room inside a house is a bad place for a telescope. 3 Mistakes: Anyone walking around will shake the image, for one. The lights on in the room would make it impossible to see anything, for another. And, even with the best telescopes on Earth, Pluto looks like a little dot. It's too small and too far away to show much of a disk. Even Uranus and Neptune are small disks through a big telescope.
Corrected entry: After Lara has fought with Simon, the butler follows her up the stairs but halfway along he is back with Simon to turn off the music. Then he's back with Lara.
Corrected entry: Just after Lara steals the first half of the triangle, she is at the top of a waterfall, and Alex points a gun at her and tells her to give it up. She then jumps, and it pans out to a far shot of the waterfall, where you see something small and white fall the length of the waterfall. However, Lara was wearing black.
Corrected entry: When Lara enters the ancient temple, all the candles in the backround aren't lit, but shortly after the rest of the expedition arrive, the candles can clearly be seen lit up...
Corrected entry: In the scene where the leader of the Illuminati is trying to join the two halves of the triangle, he is shot by a bunch of soldiers in the distance. You can see them and their laser sights clearly as they shoot. However, when you see him being shot, you don't see any laser sight dots on his chest anywhere while he is being shot.
Corrected entry: When Alex West comes out of the shower thinking someone is in the room with him, he opens the door to find the maid. In the first shot she is holding one towel, in the next, she is holding two.
