In the movie, Gregers Gram talks about the idea that someone should make a statue of him, and put it somewhere fancy, like in front of City Hall in Oslo. This is a clever joke, as there really is a statue of Gregers Gram outside Njårdhallen (the Njaard sports hall).
The producers wanted to use members of His Majesty The King's Guard as Nazi extras due to their marching and military drill skills. However, army commanders refused because they didn't want serving members of the King's Guard to dress up in Nazi uniform or portray Nazis.
In one of the scenes, Gregers jokes about his own death by saying, "If anything goes wrong this time, please shed a tear for me. And make sure my statue is erected at a suitable place - by the city hall, for instance". This quote is taken from a letter Gregers wrote to Tikken just a few weeks before he died. In 1995 Max was present when a bust of Gregers was erected outside the Njaard hall in Oslo.
