The next month, Andrews claimed it was"too late" to make the film, claiming too much time had passed for the project to be possible. With Hathaway enthusiastic about a third film but Andrews skeptical about it, can the project happen? Will Andrews miss it? Worst of all, will Disney opt for a reboot without either of the original actors? In this age, anything is possible.

‘Paddington In Peru’

The first twoPaddingtonfilms are modern classics. Centering around the loveable bear from Peru who arrives in London to live with the Brown family, the films are unabashedly positive and sweet, two heartfelt and endearing adventures that no one can resist.

A third film is a no-brainer, especially afterPaddington 2’s critical acclaim and commercial success. In June 2022,Paddington in Peruwas officially announced, as was the film’s new director,Dougal Wilson. The film is set to begin production in early 2023, hinting at a 2024 release. However, there are no details about the plot or returning cast, although the title implies the ever-polite bear might be leaving the Brown family behind in search of some adventure back home.

‘National Treasure 3’

Although theNational Treasurefranchise recently came back with the ill-fated television spin-offNational Treasure: Edge of History, the main series might be coming back for a third round. In August 2022, producerJerry Bruckheimerconfirmedthere are talks for a third film and even a script written. He also claimed he would be passing the script to series starNicolas Cageshortly.

Later that year, during promotion for the show, actorJustin Barthaconfirmedthere is indeed a screenplay for a third film. There’s no formal news about the third film, so it all remains speculative as of now. However, with Bruckheimer on board, it might only be a matter of time before Ben Gates returns to the big screen.

Although both films were commercially successful, a third entry never materialized. The first movie became a hit Broadway show, reviving interest in the series, but it wasn’t until Disney+’s arrival that the third film was officially greenlit in 2020. In Late 2021,Sister Act 3found its writer and directorinTim FederleandMadhuri Shekar. A year later, in October 2022,Goldberg claimedshe was “waiting for the script at the end of the month.” With no further developments or casting news other than Goldberg’s return, fans won’t see this long-awaited sequel until 2024 at the earliest.

‘Now You See Me 3’

TheNow You See Mefranchise took everyone by surprise. As two classicheist movies where the heroes score big, the duology became popular with audiences, grossing more than$350 millionworldwide despite lukewarm reviews from critics. The franchise also attracted A-list talent, includingJesse Eisenberg,Woody Harrelson,Mark Ruffalo,Michael CaineandMorgan Freeman.

After years of silence –Now You See Me 2came out in 2016! – the franchise came back to life in September 2022 with the announcement thatRuben Fleischerwould helm the threequel. Fleischer had already worked twice with Eisenberg and Harrelson in theZombielandfilms, so he’s a logical choice to direct. However, there’s still no official confirmation about the actors' return, although they’ll likely be back, especially now that Fleischer is behind the camera.

‘A Quiet Place 3’

The firstA Quiet Placemovie was a bonafide hit, grossing$340 millionagainst a $17 million production budget and earning near-universal acclaim. The sequel came three years later, after multiple delays due to the pandemic, earning positive reviews and grossing nearly $300 million at a time when cinemas were just getting back to business.

During the second film’s promotion,Emily BluntstatedJohn Krasinskiplanned to make a third film in the series. Nearly a year later,Krasinki officially announced the third film, hinting at a 2025 release date. However, it’s unclear if Blunt will reprise her role.
