The Expendables (2010)

Continuity mistake: After the plane is docked Stallone and Statham enter the customs agency. Statham is wearing a camera on his neck with a small lens, he even shows it to the customs agent. After leaving the customs they walk across a square. The camera now has a big zoom lens attached to it. Statham is not wearing a lens bag. Where did he get that lens from? Also strange is that the lens is set in manual focus instead of automatic. Yet the picture stays focused even zooming in. This is not possible without looking at the screen. Plus the camera is turned off in the close up shot, with the image on the LCD composited in. (00:28:15 - 00:30:45)

Whitehouse

Revealing mistake: Towards the end of the movie, when Steve Austin is on fire during the fight, you can see it is a stunt man wearing a burn suit for a split second.

Continuity mistake: Paine punches Sandra and bruising appears immediately. However, when we see Sandra shortly after, she has no bruising at all. (00:56:20 - 00:57:05)

Trivia: Sylvester Stallone sustained 14 injuries during filming, including breaking a tooth, rupturing his ankle and getting a hairline fracture in his neck that required the surgical insertion of a metal plate. He even had bronchitis and shingles during the shoot.

Trivia: During the car chase, Dolph Lungren's character is holding the same type of gun that Thomas Jane used in the Punisher, which Dolph did his own version in the 1980's.

Trivia: Wesley Snipes was the first choice for the role of Hale Caesar, but couldn't accept because his tax issues made him unable to leave the United States.

Pirate leader: Drop your guns!
Lee Christmas: Fat chance.
Barney Ross: Why do they always say that?

Mr. Church: Only thing you need to know is the job's real, and the money's real.

Hale Caesar: What happened to you?
Barney Ross: I got my ass kicked.

Question: What weapon does Hale Caesar use during the final fight? Is it a modified version of the AA-12 or a custom-made piece for the movie?

Question: Why did Barney refuse to take the job to take out Monroe?

Question: Where did they get their training? I assume Christmas was SAS, but what about everyone else?
