Madelyn Cline Ignites “I Know What You Did Last Summer” Trailer Launch

Madelyn Cline makes a fiery impression at the “I Know What You Did Last Summer” trailer launch, setting a thrilling tone for the upcoming series.

On June 14, 2025, Madelyn Cline brought a bold and playful energy to the trailer launch event for the highly anticipated “I Know What You Did Last Summer” series, held at the Singleton Theater in Los Angeles. The actress, known for her captivating presence, showcased a striking look that was both chic and perfectly on-theme for the horror-thriller revival.

Cline commanded attention in a vibrant red mini-dress, featuring a unique, voluminous detail at the hips that gave the garment a sculptural quality. The strapless design highlighted her décolletage, and she paired the dress with minimalist black stiletto heels, elongating her legs. Her blonde hair flowed in loose waves, adding to the allure, while her makeup remained fresh and radiant.

Joining her at the event, and adding to the visual narrative, was another individual in a contrasting yet equally compelling ensemble. This person wore a long-sleeved black lace top paired with a layered black skirt that incorporated intriguing cut-outs or embellishments, styled with dramatic black knee-high boots. Their dark hair and intense gaze provided a striking juxtaposition to Cline’s brighter aesthetic. The duo’s dynamic poses against the “I Know What You Did Last Summer” branded truck, featuring chilling imagery and text like “I SCREAM, YOU SCREAM, WE ALL SCREAM…” and “A TASTE YOU’LL DIE FOR,” perfectly captured the essence of the horror genre.
