Looper is a 2012 action/science-fiction film directed by Rian Johnson (Brick, The Brothers Bloom). Joseph Gordon-Levitt stars as Joe, a hitman who works in the year 2044 as a "Looper", a specialist in eliminating individuals who have been sent back in time from 2074. Joe's world begins to fall apart when he recognizes that one of his targets is his older self (portrayed by Bruce Willis) and allows him to escape. The film's cast included Emily Blunt and Jeff Daniels.
The following weapons were used in the film Looper:
The main weapon used by Loopers in the film like Joe (Joseph Gordon-Levitt) and Seth (Paul Dano) is a futuristic shotgun dubbed the "Blunderbuss". The pump action firearm is fitted with a futuristic barrel sheath. It bears a close resemblance to the 18th Century firearm it takes its name from. The weapon is mentioned by Kid Blue to be short-ranged, capable only of hitting targets 15 paces away, but unlike a real Blunderbuss, it is capable of firing multiple rounds. While largely custom made (the handle, for example, is "a Waterjet piece clad with the custom wood grips"), a large part of the barrel of the "Blunderbuss" is the Yankee Hill Machine Company YHM-5005 12.520" Smooth Series Forearm (Rifle Length) with hand-machined parts on the front and rear of the forearm. The front of the barrel also features what is most likely a Yankee Hill Machine Company YHM-262 Fixed Bipod Stud.
Remington 870 Field Gun
Sara (Emily Blunt) uses a Remington 870 Field Gun to protect her farm from intruders. She specifically mentions that the shotgun is a Remington 870.
Mossberg 590 Cruiser
When a thief tries to steal a suitcase, a man draws and fires what appears to be a Mossberg 590 Cruiser.
A nickel-plated and wooden gripped version of the BFR is carried by Kid Blue (Noah Segan). Prop Master James Kroning mentions in an IGN video that the rear sight was removed to provide better balance when spinning the pistol and to facilitate fanning of the revolver. Fixed sights were sculpted in place of the rear adjustable sight.
In Old Joe's flashback, he uses a Brügger & Thomet MP-9 during a drive by in Shanghai.
Heckler & Koch MP5A5
Old Joe is seen holding a Heckler & Koch MP5A5 with a KAC forend when he confronts Abe. This may be a continuity error, as he is never seen carrying the MP5 as he is going through the building with his twin P90s, and he is shown reloading before he confronts Abe, despite never having used the weapon.
