With the release of Insidious: Out of the Further, the hit horror franchise now spans six films. Because the series includes two prequels, the chronological timeline differs from the original theatrical release order.
To watch the story unfold in narrative order, start with Insidious: Chapter 3 and The Last Key, followed by the original Insidious, Chapter 2, The Red Door, and finally the new 2026 installment. Most films are available to stream on platforms like Peacock and Max, or can be purchased digitally.
