Finnish national television channel TV2 is airing movie "Meidän poikamme merellä" on June 5th 2010. The latter part of the movie, filmed in 1933, take place in a Navy wargame, "Iku-Turso" playing the part of enemy submarine. Interesting enough the same sub played the part of German submarine in "Morgenrot" (1933)! The movie is not available on DVD, only in VHS. So if you happened to visit Finland or know someone, make sure you get a copy of it. ;=)
