Universal’s Jem and the Holograms feature will be released October 23, 2015, according to The Hollywood Reporter.  Aubrey Peeples (Nashville) will appear in the starring role, with Stefanie Scott, Aurora Perrineau, and Halyley Kiyoko as the Holograms.  Ryan Guzman, Molly Ringwald, and Juliette Lewis will also star in the film. 

The live action film, to be directed by Jon Chu, was announced earlier this year (see "'Jem & the Holograms' Live-Action Movie").

Merch for the Hasbro property will definitely flow.  IDW revealed at the Diamond Retailers Breakfast at New York Comic Con that it has the license to produce Jem and the Holograms comics, with dates and creative teams to be announced, according to Comic Book Resources.  The company also released the accompanying teaser image via CBR.

And Hasbro will also be releasing new products.  It has been producing limited edition Jem dolls for San Diego Comic-Con for the last two years (2014 version shown here).
