Actor-Shared Background: Clyde's hand was blown off during his deployment in Iraq. In Real Life, Adam Driver was a Marine before becoming an actor; he was supposed to be deployed to Iraq, but broke his sternum before it happened and was medically discharged.
Box Office Bomb: The movie cost $29 million to produce, and grossed $27 million in the US and $41.5 million globally. It was released at the tail-end of one of the most apathetic summer box offices in years.
Casting Gag: Jack Quaid and Brian Gleeson are both sons of famous actors, Dennis Quaid and Brendan Gleeson respectively.
Deleted Scene: A "Positive / Negative" bit with the Logan brothers visiting Joe Bang in prison and a prisoner tap dancing on a table during the Prison Riot.
Fake American: The English Daniel Craig as Deep South Joe Bang. Ditto with Brian Gleeson, an Irish actor playing Joe Bang's even more redneck brother Sam.
