"The Host," directed by Andrew Niccol and based on Stephenie Meyer's novel, struggled at the box office for several reasons. Firstly, it faced stiff competition from other releases and lacked the strong marketing push typical of Meyer’s "Twilight" franchise. Additionally, the film received mixed reviews, with critics citing its pacing and character development as weaknesses. Audiences may have been skeptical due to its sci-fi premise and departure from the romance-focused themes of Meyer's previous works, leading to lower interest and attendance.

In the movie "The Host," directed by Bong Joon-ho, the monster is a giant, mutated creature that emerges from the Han River in Seoul, South Korea. The creature is a result of pollution and scientific negligence, specifically linked to a toxic dumping incident by the U.S. military. It has a grotesque appearance, with a long body, large limbs, and a wide mouth filled with sharp teeth. The monster captures a young girl named Hyun-seo, prompting her family to embark on a desperate mission to rescue her while navigating the chaos unleashed by the creature.
