You should watch "Orphan" (2009) first, as it establishes the original story and characters, including the eerie backstory of Esther. "Orphan: First Kill" (2022) is a prequel that provides additional context and reveals more about Esther's origins. Watching them in order enhances the overall experience and understanding of the narrative twists. However, both films can be enjoyed independently, but starting with "Orphan" will give you a better foundation for the sequel.

"Orphan: First Kill" is a prequel to the 2009 film "Orphan." The film explores the backstory of the character Esther, also known as Leena, detailing her escape from a psychiatric facility and her subsequent impersonation of a missing child. It delves into her origins and the events that lead up to her encounter with the Barnard family, providing deeper insights into her character and motivations before the events of the original film.

"Orphan: First Kill" is a psychological horror-thriller film, but it is not based on a true story. It serves as a prequel to the 2009 film "Orphan," which follows the character Esther, a woman who poses as a child. The narrative is fictional and draws inspiration from themes of deception and identity rather than real-life events. It explores Esther's backstory and her manipulative nature, but the elements of the plot are created for entertainment purposes and not derived from actual occurrences.

In "Orphan: First Kill," Esther, whose real name is Leena, is portrayed as a 9-year-old girl. However, the character is actually a 33-year-old woman with a rare condition that causes her to look like a child. The film serves as a prequel to the 2009 movie "Orphan," further exploring her backstory and the lengths she goes to maintain her deception.
