If you were not already aware that Peter Berg (of Friday Night Lights) directed Lone Survivor, then the trailer will make that fact obvious. Explosions in the Sky (or something exactly like it)? Check. Taylor Kitsch? Check. A group of men drawn together by a common cause that teaches them to love one another like brothers? All the checks. Really, the only differences are the cause (fighting the Taliban) and the remarkable facial hair on every actor. Did you know Mark Wahlberg could grow a beard like that? Do you think he actually grew it? Discuss.
