After the trailer dropped, fans took to social media to express their excitement, with one person commenting on YouTube: "The trailer is insane, can’t wait to see it". A second person wrote: "OMG I'M SO EXCITED FOR THIS, I’m a big fan of the original movies and seeing that the original cast is gonna be in it, it's just aaaaahhhhhh".

Meanwhile, on Instagram, one fan wrote: "I haven’t been this excited for a horror film in a VERY long time!" while another penned: "The last part just gave me chills".

What happens in I Know What You Did Last Summer?

Directed by Jennifer Kaytin Robinson, the film begins at an engagement party of Danica (Madelyn Cline), who opens up a card that reads: "I know what you did last summer".

The official synopsis goes on to explain: "When five friends inadvertently cause a deadly car accident, they cover up their involvement and make a pact to keep it a secret rather than face the consequences.

"A year later, their past comes back to haunt them and they’re forced to confront a horrifying truth: someone knows what they did last summer… and is hell-bent on revenge. As one by one the friends are stalked by a killer, they discover this has happened before, and they turn to two survivors of the massacre of 1997 for help."

Who stars in I Know What You Did Last Summer?

Leading the group of friends is Madelyn Cline (Glass Onion: A Knives Out Mystery), alongside Chase Sui Wonders (Bodies Bodies Bodies), Jonah Hauer-King (The Little Mermaid), Tyriq Withers (Don’t Tell Mom The Babysitter’s Dead) and Sarah Pidgeon (The Friend).

Despite being an "all-new" horror, viewers can expect "at least two big-hitter stars" from the '90s version – including Jennifer Love Hewitt as Julie and Freddie Prinze Jr as Ray.

What can viewers expect?

Talking to Entertainment Weekly, director Jennifer Kaytin Robinson said: “Visually, for me, it was about going back to my biggest touchstone for this movie, Jaws. I was like, ‘I want beautiful colours, beautiful setting, blue water, red blood’. For me, it's kind of like a throwback, and what I hope is that it feels like it's fresh in its nostalgia.”

I Know What You Did Last Summer is out in cinemas on 18 July.
