Saldana joins a number of other stars alongside the TV series regulars. Ashleigh Ball, Andrea Libman, Tara Strong, Tabitha St. Germain and Cathy Weseluck will reprise their roles as the Mane 6 ponies from "My Little Pony: Friendship is Magic." They will be joined by Sia, Kristen Chenoweth, Emily Blunt, Michael Pena, Uzo Aduba, Liev Schreiber and Taye Diggs.

"My Little Pony: The Movie" will be the first animated feature film from Hasbro's in-house Allspark Pictures. Stephen Davis, president of Hasbro Studios, previously said that the Allspark film unit is used for the "set of movies where we feel we have an opportunity to have a bit more control over the budgeting, financing, calendarization, marketing and creative of our films." Allspark co-produced the "Jem and the Holograms" movie, which did not perform well at the box office, so Hasbro is likely hoping for a hit from "My Little Pony."

Scripted by Rita Hsiao and "Friendship Is Magic" writer and producer Meghan McCarthy, the film takes Twilight Sparkle, Applejack, Rainbow Dash, Pinkie Pie, Fluttershy and Rarity on a journey beyond Equestria to save their home. Jayson Thiessen, who served as supervising director on more than 100 "Friendship Is Magic" episodes, will direct.

“My Little Pony: The Movie” opens November 3, 2017.
