However, a trailer is not only this. The movie company cooperated with Nico Nico Douga to tell more Japanese about this cool movie. This is an example of the tie-up.
Many texts are inserted in a screen. You may think that they are gloomy. However, this is one of the main functions of Nico Nico douga. Users of Nico Nico douga can post texts in the screen of the videos. Those almost are silly chat and impressions, but they bring about the funniness. Furthermore, Nico Nico Douga broadcasts special program in commemoration of the screening of the Iron Sky on September 15 and 20 (Nico Nico Douga performs the broadcast of the original program).
Furthermore, there is an interesting trailer one more.
This is a trailer using song of Japanese model / singer kyarypamyupamyu "Tsukema Tsukeru".
Her songs are downloaded in large numbers in iTunes of Finland. Probably this will reflect it.
