What’s the movie where a girl vanishes after entering a mirror

The movie you are referring to, where a girl vanishes after entering a mirror, is a concept that appears in several films with variations on the theme of mirrors acting as portals or gateways to other realities or supernatural realms. One notable film that closely matches this description is “Mirrors” (2008), although it was not directly mentioned in the search results. However, based on the search results, the closest related films involving mysterious disappearances, alternate realities, or supernatural reflections include “Coherence” (2013), “What Lies Beneath” (2000), and “Triangle” (2009).

“Coherence” involves a group of friends experiencing strange occurrences during a comet’s passing, including alternate realities and doubles of themselves, but it does not specifically focus on a girl vanishing through a mirror. Instead, it explores parallel universes and identity confusion triggered by cosmic events[1].

“What Lies Beneath” centers on a woman who suspects her house is haunted by a ghost, with eerie reflections and messages appearing in mirrors and water, but the plot revolves around uncovering a murder and supernatural haunting rather than a disappearance through a mirror[2].

“Triangle” features a group of friends on a yacht who encounter a mysterious ship and experience a time loop with a masked killer. The film involves supernatural and psychological thriller elements, but again, it does not specifically depict a girl vanishing after entering a mirror[3].

The motif of a girl vanishing after entering a mirror is a common trope in horror and fantasy genres, symbolizing crossing into another dimension or being trapped in a supernatural realm. Films like “Mirrors” (2008) explicitly use mirrors as portals where characters face deadly consequences, including disappearances. Other movies and stories use mirrors as metaphors for alternate realities or hidden truths.

In summary, while the exact movie where a girl vanishes after entering a mirror is not explicitly identified in the search results, the theme is closely related to films like “Mirrors,” “Coherence,” and “What Lies Beneath,” which explore supernatural reflections, alternate realities, and mysterious disappearances linked to mirrors or reflections. If you are looking for a film specifically about a girl disappearing through a mirror, “Mirrors” (2008) is a strong candidate outside the provided search results.
