The thieves are shot and stabbed several times and right afterward simply get back up with no visible injuries at all.
While some of the people in the film mentions they are in Texas in the United States and the American flag is seen in their van, you can see the drivers side is on the right side instead of the left side. Also people use European accents.
When the thug is trying to escape through the woods, the 300-foot-high tornado made of fire is obviously represented by someone running toward the camera waving a flare.
The "firenado" is absent from scenes in which the dialogue makes it clear that the characters can see it.
The story takes place in what is supposed to be Texas in the US, but the landscape and architecture are all wrong, as is the collection of European accents. Some characters go from American accents to English cockney ones, and the mob accountant suddenly starts talking as though he's from Tennessee late in the film.
