I read an interview with one of the actors a few months back, which peaked my interest, and then completely forgot about it until I saw that trailer. There's this scene where the teacher - GOD! What's his name?! - just breaks down, and it is such a raw and true moment that I promptly burst into tears.

Now I feel like I should buy a ticket for Flyboys and just stay for the trailers on the off-chance it's shown.
And then go see another movie. See! It all works out.
