The James Bond movies are known for their opening pre-credits sequences -- which usually involve Bond in some sort of massive action or destruction that may or may not be related to the rest of the movie's plot -- and the new movie 'Skyfall' promises more of the same.

In fact, a lot of the action we've seen in trailers for 'Skyfall,' the 23rd Bond entry and third starring Daniel Craig as 007, has come from the movie's opening scene, which is set in Istanbul. In a new behind-the-scenes video now online, director Sam Mendes explains a lot about what's happening in the sequence, so if you want to go into 'Skyfall' cold, you might want to avoid it.

If you're curious, however, go ahead and take a look below. And everyone can also chew on the fact that 'Skyfall' apparently has a running time of 145 minutes, which makes it as long as the series' two longest films so far, 1969's 'On Her Majesty's Secret Service' and 2006's 'Casino Royale.' Since those happen to be two of our all-time favorite Bonds, we'll take the epic running time as a good sign for this one.

'Skyfall,' in which Craig's Bond battles Javier Bardem's villainous Silva with the fate of the British Secret Service itself in the balance, opens on November 9th in the U.S.
