The We Are Marshall poster was recently released. (Thanks for the heads-up goes to my mother-in-law, who monitors All-Things-McConaughey.)
I think it captures well the movie's premise: that the community and the university combined to build themselves back from the ashes of that devastating tragedy. In it, Coach Jack Lengyl stands on the mountain where the plane crashed, looking down over the city and the university.
It's emotional, and inspiring. Click on it for a close-up view.
