She's not only in the middle of filming the final season of her hit Netflix series, Outer Banks, but she's also been simultaneously promoting this weekend's theatrical debut of Jennifer Kaytin Robinson's I Know What You Did Last Summer (2025). And that's not even half of it. Just one month ago, she happily carved out time from her existing shooting schedule and flew from South Carolina to Los Angeles in order to film a new ending for her character in Robinson's slasher.

In Robinson's legacy sequel to that film and 1998's I Still Know What You Did Last Summer, Chase Sui Wonders' Ava Brucks and Cline's Danica Richards are essentially the new Julie and Helen of Southport, North Carolina. (Spoilers ahead.) Cline's character is a former Croaker Beauty Pageant Queen à la Helen, and her (first) fiancé, Teddy Spencer (Tyriq Withers), is a wealthy loose canon just like Helen's boyfriend Barry (Ryan Phillippe) was. However, thanks to test screening audience feedback, Danica no longer suffers the same fate as Helen, and Cline didn't learn that her character would survive the newest Fisherman's wrath until the middle of June. "I only got the news that I was coming back about two-and-a-half weeks ago. We shot all those very, very end scenes about two weeks ago," Cline tells The Hollywood Reporter during a June 28 press day. June's Los Angeles-based additional photography also included a new scene where Danica visits Helen's grave and picks up a framed picture of her that's been left behind. The purpose of this scene was to further set up the surprise return of Gellar's Helen in Danica's forthcoming dream. According to Cline, the nightmarish sequence itself was not a part of the original script, but it was eventually added during the rehearsal phase of production. Gellar twice posted from the Australia set as if she was only visiting husband Freddie Prinze Jr. for Thanksgiving last year. (Prinze Jr.'s Ray Bronson joined Hewitt's Julie as two of the new film's three surviving legacy characters.) "I did not know that [dream sequence with Sarah Michelle Gellar] was happening. Jenn [Kaytin Robinson] texted me that we were going to do it. And I was absolutely floored. Gobsmacked," Cline recalls. "She then sent me the sides and was like, 'What do you think?' And I said, 'I absolutely love them, but whatever. The fact that we're doing this, write whatever you want. I'm in. I will do whatever you want.'" As for working with Gellar, Cline remains impressed with how casually she carried herself that day as both an actor and a mother. "I do believe it was one of the most iconic days of my life, and I just felt like everything conspired for us to have that in the script. It only felt right for Danica to meet and face Helen," Cline says. "It's just so special to have that stamp of approval and to be ushered in as a next generation by Sarah Michelle. [She] is, and has always been, a force." Below, during a recent spoiler chat with THR, Cline also discusses her character being a source of comic relief and how her Glass Onion director Rian Johnson bolstered that side of her. Then she addresses her name's inclusion in a couple years' worth of Spider-Man 4 casting rumors. *** To recap, you were raised in South Carolina, and that's where you shoot your show about North Carolina [Outer Banks]. And now you're starring in a North Carolina-set horror franchise. In the case of I Know What You Did Last Summer, is it a total coincidence? Yes, it's a very big coincidence, but I Know What You Did Last Summer was a North Carolina movie shot in Australia. So we're branching out. We're getting further and further away. Outer Banks, Glass Onion and I Know What You Did Last Summer all have summer vibes. Your next two movies also have summer vibes, and there's a couple past indies of yours that have summer vibes. Does this town think you're allergic to winter climate? Yeah, I think so. I do believe there's something about my vibe that doesn't give winter. I don't know if it's the fake tan or the frosted tips, but the running joke that I can't get away from boats i
