Nothing really exciting like what the other awesome people have posted, but most likely something of interest.
While watching The Last Crusade for the millionth time, I had my mother's headphones on. Now these headphones are pretty awesome, since they're stereo headphones and you can hear nearly everything going on in the background.
Well, that comes to my point, when Indy had the Grail and was running back to Henry to heal him. I could hear him mumble over and over while was pressing the grail to his father's lips, "Drink it." It's really quiet and you can barly hear it, it's so quiet in fact that even the subtitles on my DVD didn't catch it.
So yeah, it's not really
that cool, but I liked hearing it since Indy's voice had a lot of emotion on it. Adds a bit to the scene.
Same thing for KOTCS, when Mutt put his comb in that guy's soda to do his hair, at the bar him and Indy were at. I heard them at the other table say "That guy just put his comb..." and then "Oh, that ticks me off!" Makes me enjoy my favorite movies all over again, just to see if I ever missed anything in the background. Yay for awesome headphones!!
