'Knowing' Chapter 6. Greatest chapter of all time? (Spoiler alert)
Absolutely blown away on all fronts by this scene (on BD). The bleak grey day, and the rain almost make me want to shiver. The flames reflected in Nic Cage's black coat when he's trying to rescue survivors. The VFX of the plane itself, one of the most realistic effects I've seen. And that's before we get to the sound.
Knocks the beginning bank job scene of 'The Dark Knight' into a close second. (It's a shame certain scenes in 'Knowing' weren't shot in IMAX).
This is now my reference 'blow-my-friends-away-with-Blu-Ray' scene.
