The Match

A character of the same name, Hans Gruber, was played by Robert Maaser in the 1988s Die Hard played by Alan Rickman.

Space Boots -- Low-cut (below the ankle) football boots/ soccer cleats were not invented until 1954, ten years after this movie takes place. The boots worn in the game are very modern, with the collared pair shown at 1:48:20 coming out at least 70 years after the game.

Which Way Did He Go? -- Kick-offs could not go backward in 1944. First pass had to be forward from 1883-2016.

Clothes Maketh Man -- The goalkeeper is wearing the same jersey as his team, which was (and still is) against the rules.
