'Pitch Perfect 3': Everything to know about the third musical movie

Moviegoers were still singing the tunes from Pitch Perfect 2 when Universal and Golden Circle announced Pitch Perfect 3 last summer.

Given the sequel's massive box-office success, it's little surprise that the studio behind the film waited only a month after Pitch 2's release to line up the next installment in its a cappella franchise.

With Pitch 2 still in theaters, The Hollywood Reporter confirmed that screenwriter Kay Cannon and stars Anna Kendrick and Rebel Wilson were already on board for a Pitch 3, and Kendrick took to social media to officially announce the news quickly thereafter. It didn't take long before news trickled out that Elizabeth Banks would return to the director's chair, followed by confirmations that newcomer Hailee Steinfeld and alum Brittany Snow would also be back. But that's where details on Barden Bellas 3.0 stopped.

With only those high notes to grab on to, is Pitch 3 going to be aca-awesome?

It's too early to tell, but The Hollywood Reporter has compiled all of the available information on the film (so far) into a helpful cheat sheet below for fans to stay updated. Keep checking back for news.

PITCH PERFECT 3 CHEAT SHEET:

WHO

Anna Kendrick: Plays Beca Mitchell, one of the leaders of the Barden Bellas. The actress confirmed the news with a simple caption of: "Happening #3" (see above).

Rebel Wilson: Plays Barden Bella Fat Amy. In November, Wilson officially broke the news on Ellen, saying they will start to film "next year."

Brittany Snow: Plays Barden Bella and three-time super senior Chloe Beale.

Hailee Steinfeld: Plays Emily Junk, who joined the Bellas as a freshman in Pitch Perfect 2.

Elizabeth Banks: The actress-filmmaker, who has appeared in both films as commentator Gail Abernathy-McKadden, will return to the director's chair for the third installment. Banks, who made her directorial debut with the second film and co-produced the first, will be producing along with her husband, Max Handelman, and Gold Circle's Paul Brooks.

Kay Cannon: The screenwriter penned the first two installments and will be returning to write the third script.

Much of the ensemble cast is still to be determined, including the remaining Bellas and Wilson's love interest, played by Adam DeVine. Anna Camp, whose character Aubrey Posen graduated but appeared in Pitch Perfect 2, and her real-life fiance Skylar Astin (who plays Kendrick's love interest in the film, Jesse Swanson) have also yet to sign on. But as of April, Astin said he is simply waiting for the call. "When the time comes and when it's time to pick up the phone, I know they will and they know that I'll answer," he has said. "We're pretty Zen about it."

WHAT

Plot details surrounding the third film are being kept under wraps, likely because they are still being developed. Several of the castmembers yet to sign on have spoken out about how they are waiting for a phone call to return once the details are indeed locked and loaded.

"This process is such a long one and I've been through it before between the first and second movies," Astin also recently said. "If the script was written and they knew what my role was completely and they were deciding to not let me in on it, that would be strange. But I know that's it's so in flux on a daily basis that they probably want to keep us out of it for our own best interest, and we really understand that."

With three years lapsing onscreen between the first two films, Beca, Fat Amy and three-time super senior Chloe were all presumably in their last year of college in the sequel, with Steinfeld's Emily coming in as the lone freshman Bella. Until more details are released, it's unclear what roles the graduates will have when they return and whether or not Steinfeld will get star billing.

WHERE

Since both movies were filmed on and around Louisiana State University's campus in Baton Rouge, it seems safe to assume that the franchise will return to its shooting stomping grounds if the plot brings the gang back to Barden University.

WHEN

Though at first pushed back to Aug. 4, 2017, Pitch Perfect 3 is now returning to its original date and set to hit theaters a month earlier on July 21, 2017.

The Universal Pictures film will open opposite Christopher Nolan's WWII drama -; and potential Harry Styles starrer -; Dunkirk and the comic book adaptation Valerian and the City of a Thousand Planets.

WHY

Though the cost of bringing back Kendrick and Wilson could not have come cheap (options weren't in place for the pair, who earned $2 million each for Pitch 2), sources also told THR that Universal and Golden Circle were eyeing a franchise when they locked in Steinfeld.

While the sequel wasn't as well received by critics (the first film maintains an 80 percent fresh rating on Rotten Tomatoes, whereas the follow-up has a 66 percent rating on the Tomatometer), the reviews didn't hurt the franchise's box-office success the second time around.

To date, the musical franchise has a global gross of $402 million, including 2012's Pitch Perfect and 2015's Pitch Perfect 2.

The original film was a sleeper hit, grossing $115 million on a $17 million budget. The second, which is the highest-grossing musical comedy film ever, raked in $287 million on a $29 million budget.
