What's Up With Callum?

"What's up with Callum could be a good alternate title to after son," says director. "The rave emerged on the page. I didn't expect it and I didn't know where it was going, but there it was." The film alternates between two points of view: adult Sophie (played by Emma Watson) and younger version of herself as she goes through old tapes from their trip. It felt in many ways like a representation of my journey writing the film up until that point, he said.
