The opening credits says "The work on this movie started in the early summer of the year 1940. In its important scenes it stays faithful to the historical facts and depicts mostly the tasks of the 7-year-war in which the superior character of the king had to be challenged. Especially here he grew to a height which is unique in whole history. The main quotes of the king are from his own mouth."
The closing credits show the lyrics to the poem "You black eagle" while a song with these words are sang.
The opening credits are shown below the monogram of Fredericus Rex.
