With such a beloved classic cartoon turning into a live-action film, there’s always going to be some concern expressed by fans, and Jem and the Holograms is no different. But director Jon M. Chu knew what he was up against when he took on the highly anticipated project.

Transitioning from cartoon to live-action is a tough undertaking, but Chu knew the questions he had to ask before embarking on his new film. “There is a shift when you change the medium, so how do you ground this?” he asks in an exclusive, behind-the-scenes look. “How do you relate to her?”

The movie’s cast, which includes Molly Ringwald, Aubrey Peeples and Hayley Kiyoko, gives E! News inside details about what fans can expect from the forthcoming movie and why fans will be able to relate it.
