Sin City 2 had a very basic marketing plan. Interviews, trailers, TV spots, sneak peeks, and etc. The marketing team utilized Adult Swim for some trailer views. That is a good way to reach some demographics from the age of 14 to the early thirty's. They also had music star Lady GaGa in the movie so they marketed her involvement in the film as well. Billboard even made a post about her being in the movie. This the link: https://www.billboard.com/articles/news/6191120/lady-gaga-sin-city-dame-kill-for-trailer . They also had actual billboards out in public and released a theatrical poster as most films do.
