The 1990s movie classic I Know What You Did Last Summer is getting another sequel treatment, starring Outer Banks' Madelyn Cline. . For fans of the OG film, Jennifer Love Hewitt and Freddie Prinze Jr are set to return from the original movie in their original roles. First Cruel Intentions gets a reboot, now this! We just got our first look at the sequel and it looks so creepy, so good, and so, so nostalgic.

Last year, Sarah Michelle Gellar sent waves through the fan community by posting on Instagram from the set, so, who knows, maybe her role could be bigger than we think.

She posted a picture of a director's chair from the set, with the witty caption “Scooby Doo 3 coming soon”, referencing the other famous movie she appeared in with her now husband. Fans will know Sarah's character was brutally murdered by the serial killer stalking a teen friendship group. But will she also make a return?

Well, it's hard to say. The movie's director (and friend of SMG) Jennifer Kaytin Robinson reposted Sarah's story, saying: “before you dm me, she refuses to be not dead.”

When People asked Sarah if she was returning for the sequel, she responded “I am dead”. "My best friend [Jennifer Kaytin Robinson] is directing it, so we joke that I have an unofficial job, which is I am continuity," she said. "So I'm always the one telling her, 'Well, that would happen, or that wouldn't happen with those characters,' so I do have kind of an unofficial job title."

I Know What You Did Last Summer sequel plot

IMDB's plot synopsis reads: "A group of friends is terrorised by a stalker who knows about a gruesome incident from their past."

So the premise is quite similar to the earlier movies, which saw a group of young people grapple with a secret and a menacing stalker and serial killer who plans to make them pay for what they did. It's not clear how the new cast will fit into the story from the previous movies, if at all, and what storylines the returning cast will have. Will Freddie Prinze Jr play the father of one of the younger cast? What will Jennifer Love Hewitt's character arc be? We'll have to wait and see.
