Stupidity: Captain Poison has a fairly good idea of where Solomon buried the diamond. We know this since when he leads the captured Solomon to the spot, there are already several holes dug looking for it. Despite knowing roughly where the diamond is - down to a relatively small area - he makes no serious effort to excavate the ground, instead contenting himself with a handful of incredibly shallow holes.

Factual error: At the end of the film when Solomon is in London we see a bendy bus behind him. The problem with this is that the film is set in the late 90s, but bendy buses were only introduced in London in 2001.

Factual error: Throughout the film Danny Archer wears a Breitling Chrono Avenger. The problem with this is that the film is set in the late 90s but the Chrono Avenger was only released in 2001.

Other mistake: At the start of the film Danny is caught trying to smuggle diamonds into Liberia. The Liberian border guards catch him, but somehow he ends up in a Sierra Leone prison instead of a Liberian one.
