Carla Gugino describes how The Space Between Us feels epic in scope, but at its core, it is about how the main characters have isolated themselves in very specific ways. She explains how her character, Kendra, develops a close bond to Gardner, and reveals that she would go to the ends of the Earth in order to keep him safe. Carla believes the movie will appeal to many people, because it has a good story and will take them on a moving and funny adventure.
