Creator Jenny Han says she filmed special scenes with Lola Tung and one of her co-stars "because I like to keep surprises for the audience. That's really hard in this day and age. As movies get filmed, people see the whole movie, and I think it takes away from some of the excitement around it when you have all these spoilers. So that was my way of trying to protect the story for the audience."
