Insidious (2010), directed by James Wan and written by Leigh Whannell, marked the beginning of one of the most successful modern horror franchises. With its chilling atmosphere, creative use of sound, and terrifying take on astral projection, the film became a cornerstone of supernatural horror in the 2010s.
Detailed Summary
The Lambert Family’s New Home
The film opens with Josh (Patrick Wilson) and Renai Lambert (Rose Byrne) moving into a new house with their three children, including Dalton (Ty Simpkins). Renai begins to experience strange occurrences — books falling, strange whispers, and moving objects. At first, she believes the house is haunted.
Dalton’s Mysterious Coma
One morning, Dalton climbs into the attic, where he encounters something unseen and sinister. The next day, he doesn’t wake up. Doctors are baffled: Dalton is not in a coma medically, but he won’t respond to any stimuli. Three months pass, and the family is emotionally unraveling.
Moving Doesn’t Help
Renai convinces Josh to move, thinking the house is cursed. But the paranormal activity follows them. Renai hears voices through the baby monitor, sees a strange man in the baby’s room, and witnesses ghostly figures roaming the halls. This moment confirms that the problem isn’t the house—it’s something attached to Dalton.
Enter Elise Rainier and the Spectral Investigators
Josh’s mother, Lorraine (Barbara Hershey), contacts a psychic, Elise Rainier (Lin Shaye), and her two assistants, Specs (Leigh Whannell) and Tucker (Angus Sampson). Elise immediately senses a dark presence in the home and reveals that Dalton isn’t in a coma at all. His consciousness has left his body — he is an astral projector who has wandered too far into a dark dimension called The Further.
The Further
Elise explains that The Further is a realm of lost souls and demons, drawn to Dalton’s body because it’s an empty vessel. Dalton is trapped there, and one particularly malicious entity, known as The Lipstick-Face Demon, wants to possess him.
Movie Ending
Elise hypnotizes Josh to help him enter The Further, since he, too, has a hidden gift for astral projection — something he’s long repressed due to childhood trauma. Inside The Further, Josh encounters horrific spirits: faceless figures, a ghostly family frozen in time, and finally, the red-faced demon lurking in its lair sharpening its claws to Tiny Tim’s unsettling “Tiptoe Through the Tulips.”
Josh finds Dalton chained in the demon’s realm and manages to free him. The two escape, chased by vengeful spirits desperate to cross into the living world. They return to their bodies just as Elise performs a ritual to close the connection.
For a brief moment, everything seems fine — Dalton wakes up, the family reunites, and the house feels peaceful again. However, Elise senses something is wrong. She takes a photograph of Josh, who suddenly grows agitated. Elise realizes, in horror, that Josh never truly returned — the man before her is possessed by the ghost of an old woman who haunted his childhood (known later as the “Bride in Black”).
Josh (or the entity within him) strangles Elise to death. When Renai later enters the room, she finds Elise’s body and the photograph that reveals the horrifying truth: the figure in the photo is not Josh, but the old ghostly woman. Renai turns around, and the camera cuts to “Josh” as he whispers, “Renai…” before the screen cuts to black.
The movie ends abruptly, confirming Josh is possessed — a haunting cliffhanger that leads directly into Insidious: Chapter 2.
Are There Post-Credits Scenes?
No, Insidious does not have a post-credits scene. The ending itself acts as the cliffhanger, perfectly setting up the sequel.

Film Music and Composer

Awards and Nominations

- Saturn Award nomination for Best Horror Film
- Empire Award nomination for Best Horror
- Several smaller horror community recognitions for its direction, music, and atmosphere
Behind the Scenes Insights
- Director James Wan and writer Leigh Whannell made the film on a tight budget of under $1.5 million — it went on to gross nearly $100 million worldwide.
- Wan intentionally avoided CGI-heavy effects, opting for practical scares and lighting tricks.
- Joseph Bishara (the composer) performed as the Lipstick-Face Demon on set, creating an unsettling presence even behind the scenes.
- Many of the film’s creepiest sounds were created using violins scraped with metal.
Inspirations and References
The story draws inspiration from:
- Real-world concepts of astral projection and out-of-body experiences
- Classic supernatural horror films like Poltergeist (1982) and The Exorcist (1973)
- The writings of parapsychology researchers from the 20th century
- James Wan’s love for old-school haunted house tales rather than slasher films
Alternate Endings and Deleted Scenes
There are no known alternate endings, but a few deleted scenes involve additional ghostly encounters in The Further that were cut for pacing. Early drafts of the script suggested Elise would survive, but the filmmakers decided her death would have a stronger emotional and narrative impact.
Book Adaptations and Differences
Insidious is not based on a book, but its success inspired novelizations and comic-style adaptations after its release. The movie’s original ideas are fully developed within the script rather than from external literature.
