Other mistake: A lot of the aircrew are wearing a 1939-45 Star medal ribbon. This medal was obviously issued after the war's end.
Other mistake: In the scene when the Zulu warriors have broken through the roof in the hospital. The British make a hole and escape through it. You can clearly see the hole that they are going to cut open because it is a different color.
Other mistake: The title sequence reads, "Base on the novel Red Alert" instead of "Based on the novel Red Alert" (00:02:20)
Other mistake: When Eliza throws the slippers at Higgins, one bounces off him and falls in the area of the doorway and the other lands in the middle of the hall. One slipper is seen in the hall in two different scenes, then when Higgins goes to pick them up they are both together in the hall.
Other mistake: When Morgan is leaving his house at the beginning, he remembers to put the garlic back on the door. He drops his bag of stakes next to one of the bodies he plans to put in the back of his car. After putting the garlic on the door, he never picks the bag up. In fact, the bag somehow disappears in the process. It's not in the car, as you can see it's empty as he puts in the bodies.
Suggested correction: After he replaces the garlic, he is moving away from the door. There is a cut, and he is walking in the opposite direction away from the garage. There is obviously a time jump between the shots. He undoubtedly put the bag in the front passenger's seat.
Other mistake: When Charles is buying the car, he says to the dealer, who knows Charles very well, that the phone should be on the left, and the dealer, who knows what's coming, says of course, and agrees that it must be done before delivery tonight. When the car arrives, the phone is still on the right.
