Blooper

Early in the film, Frank is talking to Rafe near his animals. Frank's beard is clearly heavy and grown in. In the very next scene, Frank is seen having drinks with members of the ship's crew. While the beard is not gone, it is now much less grown in. In the following scene, which is set just moments after Frank's round of drinks, he encounters Dr. Taylor. His beard is now fully grown in again.

When Frank is driving out of the jungle, his trucks licence plate is splattered with mud in the long shots, but clean in the close-ups.

When Loffler shoots the two in the bridge one falls out of his chair and Barnett remained seated when killed. Moments later when they realize the ship is turning they try to radio Barnett and the shot in the bridge shows him dead in the other chair.

Officials would not be reading a prisoner their Miranda Rights after they are placed in custody in a cage, even a Nicolas Cage.

Dr Taylor wears her Service Dress Blue uniform to meet the ship. While SDB is an authorized travel uniform, it's highly impractical for the climate. She would have been authorized to travel in Service Dress Whites or even civilian clothes, based on the mission. At worst, she could have changed into a working (camouflage) uniform.

In the opening scene, the viewer is told Frank is in Brazil. However, in the subsequent scene after capturing the cat, some may think he and the driver are speaking some Spanish. "Gato fantasma" and "Senhor" are correct words in Portuguese.

At the dock in Brazil, all the workers are speaking Spanish and the subtitles say they are speaking in Spanish. The boat is supposed to be owned by a Mexican company, crew members may speak Spanish.

The US Marshall service does not use ships to transport prisoners internationally. It runs the only government owned airline, the Justice Prisoner and Alien Transportation System, to exclusively move prisoners.

The whole plot of the movie hinges on Loffler not being able to fly, so the government owned airline option is out.

The Marshalls try to justify transporting the prisoner by ship instead of plane saying the prisoner has a brain malformation that can cause a rupture at high altitude, hence the need to go by boat. However, all modern commercial airplanes maintain cabin pressure at 12-13 PSI, which is the equivalent of the mountainous region the Marshalls claimed the prisoner had been hiding.

This was mentioned in the movie and the explanation is the need to be extra careful, not take chances and monitor him frequently.

In the last few minutes of the movie, an injured guy walking with crutches and smoking a cigarette in the ship's engine room chastises a mechanic stripping a bolt or something, says "there's already enough diesel in here," yet he's smoking.

During the scene showing the ship leaving Brazil, the caption saying "1993 nm from Puerto Rico." In fact, behind the ship is the dock area of Old San Juan, Puerto Rico (filmed in PR).

Jaguars have incredibly acute sense of smell. It is very unlikely that an experienced hunter like Frank Walsh would smoke a cigar while waiting in a blind for one to appear.

Frank tells Rafi that only tigers and polar bears will hunt and kill men. Leopards and hyenas will also hunt men, and as a big game hunter, Frank should have known this.

Scuddy states that he served in the "Merchant Marines" Any mariner who has sailed as long as he claims would know the proper name is the Merchant Marine and the people who sail in it are referred to as mariners, not marines.

Loffler was in the Navy (and a Navy SEAL) per the description of him by the lawyer. Later, on the radio, he says he was never a "good Soldier". A Sailor (especially a Navy SEAL) would never refer to himself as a Soldier (Army).
