Here's Everything We Know About Amazon's Revival of I Know What You Did Last Summer

Similar to its 1997 predecessor, I Know What You Did Last Summer will follow a group of teenage friends on the one-year anniversary of the fatal car wreck that plagued their graduation night. After the group receive a threatening text from an unknown number, they band together to hunt down their mystery stalker, uncovering unsettling secrets about their small town and peers in the process.

It's spooky season, and Amazon Prime understood the assignment. Season one of I Know What You Did Last Summer is slated to premiere on the streaming platform on Oct. 15, 2021, right on time for Halloween!

I Know What You Did Last Summer will feature Madison Iseman, Bill Heck, Brianne Tju, and Ezekiel Goodman as the main players. Ashley Moore, Sebastian Amoruso, Fiona Rene, Cassie Beck, and Brooke Bloom will also star in season one.

Unfortunately for viewers, Amazon Prime is jumping on the week-to-week release bandwagon instead of debuting the entire season at once. Season one of I Know What You Did Last Summer will run for eight episodes, with the first four dropping on premiere day (Oct. 15). After that, Amazon Prime will release new episodes every subsequent Friday, with the finale airing on Nov. 12. There's no word yet as to how long each episode will be. Assuming the runtime will follow other Prime TV originals, fans can expect 40- to 60-minute episodes.
