It’s hard to believe that it’s been over a decade since the first Insidious film was released, following the horrific challenges faced by a couple (Patrick Wilson and Rose Byrne) who must defend their son against the malevolent paranormal forces that have invaded their home. Created by James Wan and Leigh Whannell, the long-running franchise follows the lambert family and paranormal investigator Elise Rainer (Lin Shaye) through paranormal worlds, psychic visions, and a franchise timeline that has been anything but traditional.
Whether you’re rewatching the Insidious films or diving in for the first time, there are two options for the viewing order: following the straightforward release dates, or letting the story unfold chronologically. You can’t go wrong either way, but if you prefer to understand all of the prequel backstory before getting invested in characters, then you might enjoy a chronological viewing.

Insidious Movies in Chronological Order of Events
This might look confusing, but here’s how it breaks down: the second film is a sequel to the first, and the third and fourth are consecutive prequels that lead directly into the first film.
Half of ‘Insidious: The Last Key’
While much of The Last Key is set following the events of Insidious: Chapter 3, the film also heavily features flashbacks to Elise’s childhood, where we witness her traumatic childhood – not just because of the spirits she sees everywhere, but her abusive father. The Last Key is the most Elise-centric film in the franchise, exploring her family connections, her past with Specs (Whannell) and Tucker (Angus Sampson), and untangling a deadly secret from her childhood in Five Keys, New Mexico. Aside from the flashbacks, The Last Key also introduces Elise’s nieces, one of which shares her psychic gifts.
‘Insidious: Chapter 3’
If you came to the franchise hoping to see The Conjuring star Patrick Wilson get spooked again, you’d want to skip this one. It doesn’t feature Wilson, or his co-star Rose Byrne, at all. Instead, it answers the question: What was the demonologist Elsie Rainier (Lin Shaye) doing before she stepped into the Lambert house? It turns out, she was pretty busy getting coaxed out of retirement by a teenager who wanted help contacting her deceased mother. She tries not to engage with the girl once she realizes that a demonic spirit is hunting her but soon finds she can’t disengage.
This film ends on a classic cliffhanger of “she thinks everything is okay, but it’s not,” setting up the next chapter.
The Other Half of ‘Insidious: The Last Key’
The fourth installment in the franchise takes place after Chapter 3, but with flashbacks to Elsie’s childhood. Considering Elsie has been a wise older medium who must help protect the Lambert family in the previous films, this new angle on her character is fascinating, especially if you are curious about the origins of someone who can communicate with nonhuman entities.
The most crucial detail about this film, in terms of its bearing on the rest of the franchise, is what happens toward the end. While she is battling demons, Elsie opens a door and sees a young boy, Dalton Lambert, trapped in a room. She leaves this boy but has a dream that night that he is battling a demon. Then she wakes up to a phone call from Lorraine Lambert, the boy’s grandmother, requesting her help. This overlap with the child at the center of Insidious: Chapter 1 brings the series full circle.
‘Insidious’
When Josh (Wilson) and Renai’s (Byrne) son, Dalton (Ty Simpkins), falls into an inexplicable coma, the doctors quickly run out of answers. Desperate and exhausted from their fruitless stay at the hospital, the couple takes Dalton home. Once there, they experience increasingly disturbing paranormal happenings and eventually enlist the help of Elsie, a woman who, if we’re following these films chronologically, we already know quite well when she shows up to help. When a demon takes control of Josh’s body and murders Elsie, it’s more tragic for what we know about her childhood and how we’ve grown more attached to her. In either viewing sequence, the fact that Josh kills the person who is there to help his son survive highlights the show’s commentary on the roles that men play in domestic spheres.
‘Insidious: Chapter 2’
In this film, the Lambert family must contend with Josh’s possession and the legal ramifications of his physical body having murdered Elsie. Even from beyond the grave, Elsie, summoned by one of her colleagues, helps the family piece together the mystery of what happened while protecting them from the imminent threat that the demon still poses. Sitting squarely in the middle of the franchise’s overall narrative, the second film encapsulates the ebb and flow to the Lambert family’s terror, and the terror that radiates out around them into the lives of the people with whom they associate. Whether viewed as the end or the beginning, there is nothing completely reassuring about this film. As the family is reunited, Elsie’s spirit gasps at something unseen, propelling the drama toward its perpetual malaise.
To truly get at the heart of the concept of evil itself being insidious, the story requires the extra space to stretch out, touch multiple generations, and eschew the predictability of linear time.
‘Insidious: The Red Door’
Finally, at the end of the journey is Insidious: The Red Door. The last film chronologically and by release date, The Red Door, takes place 10 years after the first film, and it’s revealed that Josh and Renai Lambert have divorced. Josh heads east to drop his son, Dalton, off at school. After seeing a ghost while attending a frat party, Dalton accidentally re-enters The Further and learns about astral projection from a YouTube video by the late Elise Rainier. Dalton’s traumatic childhood memories from the first two films resurface and Josh calls on Renai to help them. Josh eventually intentionally returns to The Further and rescues his son. Hopefully ending their family’s haunting for good.
However, a post-credits scene shows that The Further may still be around as the light above the infamous red door flicks back on.
What’s Next for the Insidious Franchise?
Currently, there are two more Insidious movies in the works. In May 2023, it was announced that Kumail Nanjiani (The Big Sick) and Mandy Moore (This Is Us) would star in a spin-off from Jeremy Slater (Moon Knight), titled Thread: An Insidious Tale. The movie would have Nanjiani and Moore play a husband and wife who cast a spell to travel back in time in order to prevent the death of their young daughter. Unfortunately, things go awry. No news on the project has been released since the initial announcement.
In May 2024, it was revealed that Sony had dated a sixth installment in the Insidious franchise for a release on August 29, 2025. It was also reported that this project would not be the aforementioned spin-off. However, no casting announcements have been made, neither has a director been revealed.
