Dafne Keen Teases Terrifying Research for Her New Horror Movie Whistle

In simpler terms, Keen admitted to doing something quite foolish upon returning from the U.K., as he was so exhausted from jet lag that he decided to push through the day and attempt to sleep at night. He stumbled upon the concept of a “death whistle” and, feeling both terrified and intrigued, decided to watch Yellowjackets. This only intensified his fear, as Sophie also felt frightened. Fortunately, their shared fear led them to have a sleepover instead. Although he did some research on the topic, Keen believes there are misconceptions surrounding it, with some information being positive while other accounts were horrifying, like in a movie.
