Clouds - Easter Eggs & Hidden Details

The film is filled with cameos from the real people in Zach's life. The real Amy Adamle appears alongside actress Madison Iseman in a dance studio scene. Zach's sister Grace and his friend Mitchell Kluesner also appear as students. Seventy of Zach's friends and family were extras in the concert scenes, adding a layer of authenticity and tribute.

The final shot of Amy and Sammy seeing a cloud shaped like a 'Z' is based on a real event. After Zach's passing, his friends took a photo and a Z-shaped cloud appeared in the sky, which they interpreted as a sign from him.

The song that plays during the end credits, "Purple Pink," is an original song by the real Sammy Brown. It was the first song she finished writing after Zach's death, completing it on the sixth anniversary of his passing.
