While the show followed a record company owner who transformed into a glam rock goddess with the help of a holographic computer, Jon M. Chu's version follows a teenage girl who becomes a YouTube sensation after a video of her singing goes viral and she and her sisters are pressured to sell out to corporate interests in order to gain fame and success.
Aubrey Peeples plays Jerrica Benton -- a.k.a. Jem -- while Juliette Lewis plays the owner and manager of Starlight Music, which was the job Jerrica had on the TV show, but now she's the bad guy?
The whole thing is a little confusing, and really makes you wonder why the movie is even called Jem and the Holograms, until you remember that the movie was produced by Hasbro Studios who own the rights to the show.
Although the Transformers film series was based on a Hasbro toy line and animated series, and when they made that movie they kept the part about the giant robots that fight each other.
Where is Synergy? In the '80s TV show, Jerrica's father invents the awesome future-computer for the purpose of being the latest in cutting-edge holographic technology. Jerrica is able to use holograms to transform into her Jem persona through the implementation of tiny projectors in her earrings.
