Continuity mistake: Near the end of the movie, Lara Croft and Manfred Powell (Iain Glen) both draw their pistols and have them pointed at each others head. Powell suggest that the two put the guns down and settle it hand to hand. The two lay their guns down and fight. As the fight is progressing the cave is falling in around them. Laura knocks Powell out and begins to run for the exit and she does not slow down. As she makes it to the exit you can see her pistols in their holsters on her legs. This is edited from a longer sequence, as seen on DVD, but still a mistake in the theatrical release.
Question: The Director states in the commentary that there are some clues to some kind of puzzle at certain scenes (such as When Lara is doing the bungee ballet and when Alex gets knifed). What are these clues that we're supposed to be looking for - something in the background? The action? Some kind of composition? And just what is the puzzle?
