This one looks like a mixture of comedy and an introspective look at the American love of the military, and if those things are not for you I still think you will like this one, because it definitely looks like it has a lot of heart. 

Based on a true story, this film Chickie (Zac Efron) wants to support his friends fighting in Vietnam, and after a few drinks in the local bar he declares that he is going to personally bring them all an American beer. Which leads to this loveable idiot learning the truth of what his friends are facing, and it is a truth that will forever change him.

I just love little slices of history like this and really cannot wait to see it.
