'Jem and the Holograms' Finds Its Stars (Exclusive)

UPDATED: "Nashville" actress Aubrey Peeples will play the lead, and the Holograms will be played by Stefanie Scott, Aurora Perrineau and Hayley Kiyoko.

Jem is her name, no one else is the same.

In her first major film role, Nashville actress Aubrey Peeples has been cast as the lead, Jem, in the live-action Jem and the Holograms film, which is being directed by Jon M. Chu.

The Holograms have also been cast: Stefanie Scott, who starred on Disney's A.N.T. Farm, will play Jem's sister, Kimber; Pretty Little Liars actress Aurora Perrineau will play Shana; and The Fosters ' Hayley Kiyoko has been cast as Aja.

Based on the 1980s Hasbro toy line that was also a beloved cartoon, the film will be produced by Jason Blum’s Blumhouse Productions, Scooter Braun Productions and Chu. The film has been moving along quite quickly, and is already shooting.

The cartoon ran from 1985 to 1988 and chronicled the adventures of Jerrica Benton and her alter ego, Jem, a singer who fronted a band called The Holograms. When the project was first announced on March 20, producers said Jem is being reimagined "for a whole new generation with themes of being true to who you are in a multitasking, hyperlinked social media age."

Ryan Landels wrote the script, which, per the producers, centers on an orphaned teenage girl who becomes an online recording sensation. She and her sisters embark on a music-driven scavenger hunt -- one that sends them on an adventure across Los Angeles in an attempt to unlock a final message left by her father.

The production has been encouraging fan involvement through every step of the process, taking fan submissions for roles in the film and showing off fan-made art on its Tumblr. (See the first official art for the film below.)
