Post-Credits Cameo in “I Know What You Did Last Summer” Teases Major Return

Okay, I’ll explain, but try to keep up. The Amazon Prime Video series “I Know What You Did Last Summer” slips in a jaw-dropping post-credits cameo that’s already lighting up fan forums. In a scene you almost missed, the masked killer removes their signature hook mask to reveal the unmistakable face of a legacy character from the original 1997 slasher film.
Viewers who stuck around past the closing credits got more than just a blooper reel. As the final frame freezes on a foggy dock at night, the enigmatic figure drapes a bloodied hook over one shoulder and pulls off the mask to expose none other than Ryan Phillippe’s James. That bombshell moment has confirmation from two angles: eagle-eyed fans shared a screengrab on Reddit within minutes, and People magazine sources have since verified that the production quietly filmed Phillippe’s cameo in late March.
This isn’t your typical overhyped cliffhanger. It not only bridges the gap between the new ensemble led by Madison Iseman, Brianne Tju, Ezekiel Goodman and Ashley Moore, but it also signifies that the franchise is ready to weave the old guard into its modern reboot. The Hollywood Reporter adds that this tease was shot in the same Chesapeake Bay set used for principal photography, solidifying that Amazon has concrete plans for season two.
Let’s give you just enough context so you don’t feel completely lost. The series, created by Sara Goodman, reimagines the core premise of the original Jonathan Demme-produced horror: a group of teens haunted by a deadly boating accident and a vengeful killer. Unlike the linear scares of the 1997 film, this version twists perspective across multiple timelines. Season one concluded with a face-to-face showdown, but this secret mid-credits insert suggests James survived his on-screen demise and is gunning for revenge once again.
Curious how they snuck Phillippe back on set without the paparazzi swarm? Well, according to set insiders speaking to Variety, the actor signed on for a single night shoot under a non-disclosure agreement. Crew members disguised his arrival by billing him under the alias “Alex Carter.” As a result, social-media sleuths barely got wind of it until that final shot landed on our screens.
Now you probably need to reorganize your weekend binge-schedule. Will James team up with the new cast or go solo in a blood-soaked vendetta? Amazon executives remain tight-lipped, though an executive producer hinted at Comic Con that more original characters could surface. So yes, your theories about a full crossover season might actually pan out.
Enjoy pondering that twist until the official renewal announcement. Well, now you finally understand how a quick cameo can rattle an entire fanbase.
