I have been trying to track down as much information about this film as I can since it's Dutch release. It appears that this film will indeed get a theatrical release in the US after all! I have not seen an official press release on this, but after doing a bit of searching, I did run across this post on Twitchfilm.com form back in June 2015 that I missed then.
Part of that information was also listed on the films official page in June, I missed it there as well. However, it gives no date and simply states “early 2016.” I was looking around this morning and came across a bit of new information on this film, the IMDB movie page now says that it will be in theaters in the US on February 11'th 2016! There is also a listing now on the US movie ticket retailer Fandango under the title “Admiral,” but the listing has absolutely zero information and appears to simply be a placeholder. I have no clue how widespread a release it will be. It does however appear that they have dropped the “Command and Conquer.” moniker that was attached to the UK release of the film.
