Kate Winslet Still Goes By This Nickname Jack Black Gave Her During 'The Holiday'

"It was all just great fun, they're all lovely people," Kate Winslet tells Vanity Fair. "And Cameron [Diaz'] whole thing ever in life is 'How can I have the most fun possible?' So she's constantly laughing, she's constantly joking. And Jack, of course, he just does something different every take."

While rom-coms don't usually have space for improv since the movie relies on specific timing, Kate says the actor always found a way to keep everyone on their toes. "[It's] eternally refreshing," she continues. "I was always really grateful for that."

However, not only did Jack find a way to ad-lib some of his lines, but he also started a set trend that Kate Winslet follows to this day! "My onset nickname to this day is K-Dub...and Jack started it," she reveals. "That is my name, everyone at work just calls me K-Dub."

Kate admits she'd love to work with Jack Black "again and again and again," which is a sentiment he shares as well. During the press tour for Kung Fu Panda 4, he talked about how Kate Winslet is his favorite costar of all time. "When you look in her eyes, she was, like, really present," he tells Entertainment Tonight. "And I feel like if you look into my eyes, you just see a shadow of a robot."
