At some point in the production of every horror movie, a choice must be made.
For most features, this is a decision that is made during the early phases of development, as it can have a major impact on the way things are orchestrated on set, but in the case of Blumhouse’s Fantasy Island, that direction was apparently not finalized until after a first edit was presented to a test audience.
Things can move in an R-rated direction, allowing for maximum on-screen carnage, and for characters to scream obscenities as they are being terrorized; or things can lean PG-13, resulting in the reins being pulled back on content in hopes of inviting a large audience to buy tickets.
