"I Know What You Did Last Summer" is a 1997 American slasher film directed by Jim Gillespie, based on the 1973 novel of the same name by Lois Duncan. The film starred Jennifer Love Hewitt, Sarah Michelle Gellar, Ryan Phillippe and Freddie Prinze Jr., and became a cult classic of the late 90s horror genre. It's no surprise that the film has now been adapted into a TV series.

The upcoming "I Know What You Did Last Summer" TV series is set to premiere on Amazon Prime in October 2021. The series is produced by Sony Pictures Television and Original Film, with Sara Goodman serving as the showrunner. It will consist of eight episodes, each an hour long.

The series will follow a group of teenagers in a small town who are terrorized by a mysterious killer, one year after a fatal accident on graduation night. The series promises to be a modern take on the classic film, with new twists and turns to keep audiences on the edge of their seats.

The cast of the upcoming series includes Madison Iseman, Brianne Tju, Ezekiel Goodman, Ashley Moore, Sebastian Amoruso, Fiona Rene, Cassie Beck and Brooke Bloom. While the characters' names have not been revealed yet, it is confirmed that they will be playing new characters and not reprising the roles of the original film's characters.

The series is set to be a continuation of the story from the film, rather than a complete reboot. This means that audiences can expect to see some familiar themes and elements from the film, while also being introduced to new characters and storylines.

One of the most exciting aspects of the upcoming series is the involvement of Sara Goodman as showrunner. Goodman is known for her work on hit TV shows such as "Preacher" and "Gossip Girl". Her experience in crafting compelling and dramatic storylines, as well as her ability to create complex and relatable characters, makes her the perfect choice to helm this project.

Goodman has promised that the series will be more than just a standard slasher show. She has stated that the show will delve into themes such as identity, trauma and the consequences of one's actions. This means that audiences can expect a more nuanced and sophisticated take on the classic horror genre.

The series will also feature a diverse cast, with actors of different ethnicities and backgrounds. This is a refreshing change from the predominantly white casts of the original film and many other horror films of the past. The inclusion of a diverse cast reflects the changing attitudes towards representation in Hollywood and the importance of inclusivity in storytelling.

The trailer for the series has already been released, and it promises to be a thrilling and suspenseful ride. The trailer shows a group of teenagers grappling with the guilt of their past actions, while also being stalked by a mysterious killer. The tension is palpable, and audiences will be eagerly anticipating the release of the series.

The upcoming "I Know What You Did Last Summer" TV series promises to be a fresh take on the classic horror genre. With a talented cast and crew, as well as a commitment to exploring deeper themes and issues, the series is set to be a must-watch for horror fans and newcomers alike.

It will be interesting to see how the series expands on the original film's story and themes, and whether it is able to capture the same cult following as the original film. With Halloween just around the corner, there's no better time to get excited about a new horror series.
