A free movie is one thing, but a free advance screening of Ben Wheatley‘s outrageously entertaining “Free Fire“? Well, it doesn’t get much better than that, and this week, some lucky readers are going to get their chance to see the explosive action movie before everyone else.

Starring Brie Larson, Cillian Murphy, Armie Hammer, Sam Riley, and Sharlto Copley, the film (mostly) unfolds in a warehouse where two gangs meet to make a deal for some guns. Seems simple enough, but things go wrong, and soon everyone is locked, loaded, and fighting for their survival. Here’s the official synopsis:

Set in a colorful yet gritty 1970s Boston, Free Fire opens with Justine (Oscar® winner Brie Larson), a mysterious American businesswoman, and her wise-cracking associate Ord (Armie Hammer) arranging a black-market weapons deal in a deserted warehouse between IRA arms buyer Chris (Cillian Murphy) and shifty South African gun runner Vernon (Sharlto Copley). What starts as a polite if uneasy exchange soon goes south when tensions escalate and shots are fired, quickly leading to a full-on Battle Royale where it’s every man (and woman) for themselves.

The advance screenings will take place on April 12th in Portland, and April 13th in Phoenix, Dallas, Austin, Washington, Minneapolis, Atlanta, Seattle, San Diego, Chicago, Houston, Philadelphia, Boston, and South Miami.
