“I’ve been kind of an anxious wreck about who would play these characters,” Henry tells them in the video. “I truly could not feel more confident that my readers and then so many more people who don’t even know about the book are going to completely fall in love with Poppy and Alex.”

Fans of the book chimed in with their hearty approval.

"I didn’t even know it would be them (cast) and I can’t picture anyone else now," one user wrote. "This is what perfect casting feels like."

Another said: "I am personally ready to be changed as a person by this adaptation."

There's no release date set for the film.
