Continuity mistake: When Ross is standing on the ladder working on the engine you see on the left side of the plane 7 skull decals. There are 4 on top and 3 underneath. The 3 underneath are at the back of the 4 decals. Then when the plane is taxiing on the runway the bottom 3 skull decals are at the front of the 4 decals. (01:17:30 - 01:19:35)
Continuity mistake: When Ross and Galgo are in the plane taxiing to the runway (with propellers rotating), and see Ross' former team members standing in the way, the propellers are standing still. Seconds later, the propellers can be heard rotating again. (01:21:30)
Audio problem: When Smilee says they got reinforcements, Barney says "shit". But his mouth doesn't move. (01:32:00)
Audio problem: When Christmas and the Spanish man narrowly miss being hit by a shell, the Spanish man falls through the floor and says he loves it. Christmas then replies with "good keep it up" or words to those effect. However his mouth doesn't move. (01:35:00)
Suggested correction: It did move, checked it.
Revealing mistake: When the tanks are firing on the building near the end, some of the shots of shells hitting the building are reused. (01:35:00)
Continuity mistake: When Barney reaches for the revolver in the back of his belt, the way he holds it changes between shots. (01:47:40)
Continuity mistake: As Barney stands up after being shot by Stonebanks, he has his throat mic still on (black plastic round his neck). When Banks says to take the armor off, it has disappeared, only to return when he takes the armor off. (01:47:40)
Continuity mistake: During the fight at the end between Stonebanks and Barney, Barney draws blood from Stonebanks mouth, between shots this keep disappearing and reappearing. (01:48:10)
Factual error: Their 'spot' for drinking is apparently in the French Quarter because of the street signs. That said, they are drinking Budvar beer. If you know about Budvar, it is the original Budweiser beer from the Czech Republic. Budweiser sued Budvar and won, preventing them from using the name 'Budweiser', even though Adolph Busch came up with 'Budweiser' after going to Pilsner, Czechoslovakia. Budweiser being the bully, and their lawyers and all, won the lawsuit. So now the beer is sold as 'Czechvar' in the US and 'Budvar' everywhere else, meaning they couldn't be drinking it in the USA.
Continuity mistake: At the start, there is a bit of yellow tape on the glass of the helicopter that disappears between consecutive shots.
Factual error: It is stated that X-rays would ruin the oils in paintings. However, it is commonplace to X-ray paintings to see what lays beneath.
Continuity mistake: In The Expendables, Christmas has his tattoo on his right arm, However in this one it is now on his left arm.
