When you make lists about failed movies, you might focus on how bad they are, like The Room, or how few people went to see them, like Zyzzyx Road, but if you really want to define a box office bomb, you focus on how much money was lost. Most of the movies on the list of box office bombs at Buzzfeed are fairly recent, because no one spent a hundred million dollars to make a movie more than a couple of decades ago. Plus, a huge marketing and advertising budget will add to the cost that must be made up in ticket sales. Therefore, a movie you may have seen and liked can still be a bomb if it cost more than it earned. That said, you will see movies on the list that you’ve never heard of, despite advertising. They died out that quickly. Cowboys and Aliens, shown above, came in 25th.
And I genuinely love The 13th Warrior, I think the biggest problems there are: the large budget they spent on the film (still can't tell where that huge amount of money went), and marketing the film focusing on Antonio Banderas; they should have spent more time playing up the Vikings who were kick ass awesome in this film
