Revealing mistake: When Lupe Lamore puts Sanchez's iguana down on the table near the end of the movie, you can see the iguana bounce slightly. Also, it isn't breathing.
Revealing mistake: During the tanker chase scene, the characters are driving Kenworth W900B tanker trucks. The W900B series trucks have cab door latches located on the bottom, rearmost corner of the cab doors. After Bond forces another truck into the ditch, its driver can be seen climbing out of the wrecked truck. The door latch on this truck is now located just below the window. Kenworth stopped using this style of door latch in the early 1970's on the W900A, the W900B's predecessor. The truck in the ditch has been swapped out with an older W900A for the explosion shot.
Revealing mistake: When Ed Killifer is on the van leading Sanchez to jail, he hits a guard on the face with a shotgun, but the guard is already wounded before being hit.
