"The Hunger Games" had essentially ended its screening in North America, with a cumulative box office of 468 million US dollars, while its overseas box office slowly broke four hundred million. Compared to "The Avengers," "The Hunger Games" had a relatively average performance in the international box office.
Media summarized three main reasons for this.
The first is that "The Hunger Games" was also distributed by Lionsgate Films in overseas regions, which has inferior distribution channels compared to Disney and the other major studios.
The second point is that the main cast of "The Hunger Games" were not very famous internationally, and couldn't compare to the star-studded cast of "The Avengers."
The third point is related to "The Hunger Games" IP itself. The movie was adapted from a best-selling novel, but compared to universally famous best-sellers like "Harry Potter" and "Twilight," "The Hunger Games" had much less impact overseas.
