I Know What You Did Last Summer Returns with a New Sequel and Familiar Faces

I Know What You Did Last Summer is set for a chilling return with an all-new slasher instalment, directed by Jennifer Kaytin Robinson and co-written alongside Sam Lansky. Based on a story by Leah McKendrick and Robinson, the upcoming film is the fourth in the franchise and a direct sequel to I Still Know What You Did Last Summer (1998), ignoring the events of the 2006 spin-off.

The plot follows five friends who accidentally kill a pedestrian and cover it up. A year later, a mysterious stalker knows the truth and is out for bloody revenge. As bodies start dropping, the group turns to the survivors of the original Southport Massacre from 1997 for help.

Starring Madelyn Cline and Chase Sui Wonders, the film marks the return of Freddie Prinze Jr. and Jennifer Love Hewitt, who’s reprising her role as Julie. Hewitt told Parade she pushed for a meaningful return, saying:

“If I’m going to come back 27 years later, I don’t want to just be in it for five seconds. I don’t want it to just be that thing like, ‘Oh, there’s the ghost of I Know What You Did past—here she is.’ I want to carve out the time to really be in it, to make it matter for people.”

Filming kicked off in October 2024 across New South Wales. The film slashes into Aussie cinemas on 17 July 2025.
