Revealing mistake: When Lara Croft goes into the water near the end to try to save her male rival, Alex West, after he is stabbed and ground between the gears, when Lara stands up, you can see the make-up coming off her arm that covers Angelina Jolie's "Billy Bob" tattoo.
Revealing mistake: When Lara gets out of the bath, you can see a strap on her shoulder which means that Lara wasn't naked when she got out of the bath.
Revealing mistake: Towards the end, when the knife's being pulled out of someone, you can clearly see this was a retractable blade with a pre-painted blood-pattern, as the blood on the knife at his chest level doesn't change - it stays static as the knife handle rises.
Revealing mistake: In the scene in the ice cave, Lara rings the bell to break down the wall. Funny the icicles hanging from the bell never move or fall.
Revealing mistake: During the bungee scene it is meant to be night-time, but when the camera pans up to the sky light you can clearly see blue sky and clouds.
Revealing mistake: When everyone dogsleds toward their objective, you can see the filming crew's snowmobile tracks at the bottom of the screen.
Answer: This movie left a lot of holes. It was pretty much: Lara knew what to do and she did it. Perhaps there are clues in the movie, but the book explains all the puzzles in much more detail (as books do). So if you are really interested in the deep puzzles of the adventure, the Tomb Raider book is what you should look at.
