- Movie Goof (continuity error): When MacGruber is shown in his dress uniform, he has no Medal of Honor or several of the other medals he was supposed to have won as described earlier in the movie.
- Movie Goof (continuity error): When MacGruber leaves the cemetery for the second time as he beats the Dodge Neon, he puts his radio on the hood and leaves it there as he blows it up. In the later scenes you can see he still carries his radio.
- Movie Goof (continuity error): When the guy in the gray Neon yells at Macgruber (when he first sees the car), the car is an SRT-4 neon, and when he sets the car on fire, it is an SXT neon.
- Movie Goof (revealing mistake): SPOILER: After Jeff the henchman is shot in the head (and his brains etc is splattered onto a canvas) he falls onto the floor with the back of his head towards the camera - without a mark on it (no hole, no blood, no nothing).
