The four-episode series will land on Disney's streaming service just months after Inside Out 2 was released. The record-breaking sequel dived back into the mind of Riley, the teenage protagonist, as she grappled with emotions such as Joy, Sadness and Anxiety.
But how will Dream Productions fit into the Inside Out universe? Here's everything you need to know about the show.
Is Dream Productions a prequel or a sequel?
Dream Productions will take place between the events of Inside Out and this year's Inside Out 2, making the series an 'interquel'. Like both films, it will be set inside Riley's mind following her family's relocation from Minnesota to San Francisco.
The show will focus on the "inner workings" of Dream Productions, the Hollywood-style studio that creates Riley's dreams and nightmares. Another key difference is that it will be framed as a mockumentary and will lean into a more comedic tone.
The official synopsis reads: "Riley is growing up and when her memories need some extra processing, Joy and the rest of the Core Emotions send them to Dream Productions.
"Acclaimed director Paula Persimmon faces a nightmare of her own: Trying to create the next hit dream after being paired up with Xeni, a smug daydream director looking to step up into the big leagues of night dreams."
When will Dream Productions be released?
All four episodes of Dream Productions will be released on Disney+ on Wednesday, 11 December. The streaming platform is home to every Pixar film, including both Inside Out movies.
The studio has billed the spin-off show as a "limited series", which suggests there will not be a second season. However, it could pave the way for a possible Inside Out 3, which has yet to be green-lit by the animation giant.
Is there a trailer for Dream Productions?
The two-minute trailer for Pixar's new mockumentary show was unveiled on 21 November, reintroducing Inside Out fans to Riley and her warring emotions. Watch it below.
Who is in the cast of Dream Productions?
Many familiar Inside Out cast members will return for Dream Productions. Child star Kensington Tallman will be back to voice protagonist Riley, after taking over the role from Kaitlyn Dias in Inside Out 2.
Amy Poehler, Liza Lapira, Tony Hale, Lewis Black and Phyllis Smith will all reprise their roles as Riley's core emotions: Joy, Disgust, Fear, Anger and Sadness, respectively.
The IT Crowd star Richard Ayoade will provide the voice of Xeni, while Wine Country's Paula Pell will play fellow director Paula Persimmon. Other stars will include Saturday Night Live alum Maya Rudolph and Toy Story 4's Ally Maki.
Dream Productions will be written by Mike Jones, who penned Pixar's existential Soul and coming-of-age flick Luca.
Pete Docter, who directed the original Inside Out, said the series would showcase "Pixar creativity at its finest". He added: "Dream Productions offers up a treasure trove of jokes and fun as it digs deeper into one of our favorite parts of the first film, the making of Riley's dreams."
In a separate interview with Entertainment Weekly, he said it would be "unique and bold, unlike anything we've done before" and would explore "power of dreams and how they affect us in our waking life".
The only other Pixar franchises to have landed their own spin-off shows are Toy Story, Monsters Inc. and Cars.
