Aubrey Peeples is playing Jerrica, a young orphaned girl who is transformed into a rock star named Jem with her best friends, and the help of some high-tech earrings. The rest of the Holograms are being played by Stefanie Scott (Kimber), Aurora Perrineau (Shana) and Hayley Kiyoko (Aja). Ryan Guzman is playing Rio, the Holograms' manager and Jem's love interest, and Nathan Moore is portraying the thug Zipper, who works for the manager of the Holograms' rival band, The Misfits.
The story will follow the band as they set off on a musical adventure throughout Los Angeles. While it isn't known who Juliette Lewis may be playing yet, it's possible that she could be portraying Jem's artifically intelligent fairy godmother/hologram, Synergy. The actress does have rock star experience herself, fronting her own band Juliette and the Licks until 2009, before going solo.
