Studios such as Illumination and DreamWorks Animation have capitalized on this trend, building entire portfolios around franchises with the potential for regular new releases. Despite this prevalence, not every sequel achieves blockbuster status akin to “Incredibles 2.” In fact, some sequels have underperformed so significantly that they halted the momentum of once-thriving franchises. Five particularly noteworthy examples illustrate the risks inherent in producing animated sequels.

While the right sequel can spawn a hit like “Zootopia 2,” these five films serve as reminders of the potential pitfalls. Instead of generating profit, they signaled that their respective family-friendly universes had exhausted their appeal. Animation studios should take heed — their next sequel might just join this list of cautionary tales.

Consider “The Secret Life of Pets,” which premiered in July 2016. Not only did it perform well, but it also became one of the highest-grossing original films ever, raking in $886 million worldwide. With such success, a sequel was inevitable. Illumination, the studio behind the “Despicable Me” empire, aimed to recreate this triumph with “The Secret Life of Pets 2.” Given the consistent profitability of the “Despicable Me” franchise, it seemed reasonable to expect similar results.

While some fans still hold out hope for “The Secret Life of Pets 3,” the lack of recent updates suggests this sequel is on hold indefinitely. It appears these beloved characters may have retired to a metaphorical farm upstate, their adventures seemingly concluded.

Unfortunately, this title debuted as so many summer 2019 blockbusters were flopping. Though by no means a money-loser, “Pets 2” was a disappointment that didn’t reach its fullest financial potential. Its $446.44 million worldwide haul was roughly half of what the first movie made globally, while its $159.2 million domestic total made it the first fully computer-animated Illumination feature to make under $200 million domestically. Though it only cost $80 million to make and turned a profit theatrically, these weren’t figures indicating a franchise that would continue for years to come.

While some ardent fans of these films still wondered whether or not there will be a “Secret Life of Pets 3,” it currently looks like this project is shelved. With no recent news on “Pets 3,” it seems that these characters have gone to a nice farm upstate.

Once “The Lego Movie” became a hit in 2014, Warner Bros. moved quickly to further exploit the property. “The LEGO Batman Movie” and “The LEGO Ninjago Movie” each debuted in theaters in 2017. Finally, in February 2019, a proper follow-up to the original “Lego Movie” premiered in the form of “The Lego Movie 2: The Second Part.” In between the two “Lego Movie” installments, Chris Pratt (who starred as a plucky Lego minifigure named Emmet) had enough time to play Star-Lord in three different Marvel Cinematic Universe properties. That lengthy wait didn’t do “The Second Part” any favors in its box office run.

Instead, this production only grossed $105.8 million domestically and $192.3 million worldwide. This meant the sequel not only made significantly less than its predecessor, but also failed to double its $99 million budget. Suddenly, a property that was previously a cornerstone of the Warner Bros. empire was now yesterday’s news. Unsurprisingly, Warner Bros. and Lego parted ways when it came to new original movies less than a year after “The Second Part’s” underwhelming box office. Lego has since tried various times to get new Lego movies off the ground at Universal Pictures to no avail, save for the standalone 2024 arthouse documentary “Piece by Piece.”

Kids and adults alike remain as captivated as ever by Lego minifigures. However, when it comes to the “Lego Movie” franchise, that property has been gathering dust.

For so many years, the original “Happy Feet” was the biggest computer-animated movie not from an animation studio owned by either Disney or Universal. That immense box office success spoke not only to how popular penguins were in the mid-2000s, but also how much “Happy Feet” as a standalone movie had resonated with people. Warner Bros. Pictures wasn’t about to let that feature and its immense financial pull remain a one-off. Five years after “Happy Feet,” those crooning penguins returned for “Happy Feet Two,” which focused on a new generation of penguin chicks navigating feeling like outcasts.

“Happy Feet Two,” though, fell off steeply from its predecessor’s box office sum. Whereas the original “Happy Feet” was by far the biggest family movie attraction in November 2006, this follow-up opened in a crowded field for kids fare that also included “Hugo,” “The Muppets,” and “Puss in Boots.” Thus, “Happy Feet Two” only grossed $64 million in its lifetime domestic gross, less than $2 million more than the original “Happy Feet” amassed in its first seven days of North American play. With only $95.18 million from overseas markets, “Happy Feet Two” was a total financial bust.

After this project, the “Happy Feet” franchise went on ice (no pun intended) and Warner Bros. shifted focus to productions originating under its newly-created Warner Animation Group label (like “The Lego Movie” and “Storks”). At least this saga will always have the initial installment’s impressive box office records.

Elton John has never minced words about what a struggle it was to make “Gnomeo & Juliet.” On the surface, this 2011 animated film would seem like just a routine animated family movie. However, it took ages for this project to come to fruition. During that time, “Gnomeo” survived several regime changes at Disney and shifts in the studio’s animated cinema priorities. There were even times where it was reported that “Gnomeo & Juliet” was outright canned. John, though, kept believing in the project, partially because of him being a father and also because he thought his songs would excel in a “Romeo and Juliet” story. Though it became a box office success, the “Crocodile Rock” singer has alleged that Disney refused to congratulate or celebrate “Gnomeo’s” financial triumphs.

Given how long Elton John spent making “Gnomeo & Juliet” a reality, it isn’t surprising that he wanted to keep this universe going. Equally unsurprising is that Disney didn’t return for the follow-up, “Sherlock Gnomes.” Paramount Pictures handled this project, which hit multiplexes a whopping seven years after its predecessor. Unsurprisingly, any heat surrounding “Gnomeo” had long evaporated. “Sherlock Gnomes” was a box office disaster, grossing only $90.4 million worldwide, less than “Gnomeo’s” domestic total.

Much like various legacy sequels that flopped at the box office, “Sherlock Gnomes” was a follow-up nobody really asked for. It provoked neither nostalgia nor general interest from the moviegoing public. Thus, not even Elton John’s love for the “Gnomeo & Juliet” universe could keep this franchise going beyond the box office dud “Sherlock Gnomes.”

The first three “Madagascar” movies each made between $180 and $216.39 million domestically. This franchise’s core staples, like energetic atmosphere, goofy gags, and things only adults notice in the “Madagascar” films, kept this DreamWorks Animation franchise thriving at the box office. It’s no surprise, then, that DreamWorks opted to not only keep the “Madagascar” saga going, but find ways to branch it out into other potentially lucrative motion pictures. This is how the spin-off title “Penguins of Madagascar” was born. Skipper and the other three penguins had already headlined a Nickelodeon TV show, and now it was time for a (standalone) motion picture.

Unfortunately, pivoting to a wacky side-adventure focusing just on these critters didn’t prove a recipe for box office success. Opening over Thanksgiving 2014, “Penguins of Madagascar” flopped with a disastrous $83.85 million domestically. This made “Penguins,” at the time, the third lowest-grossing CG-animated movie ever from DreamWorks in North America, only ahead of “Flushed Away” and “Turbo.”

There isn’t a single reason why certain DreamWorks Animation movies flop. For “Penguins,” it seems to have simply been that this feature didn’t look engaging enough for non-family audiences, as well as competition from titles like “Big Hero 6.” Inspiring a $57 million loss for DreamWorks Animation, “Penguins of Madagascar” ensured that the entire “Madagascar” franchise has seen been shelved. The good box office times for this saga came to an abrupt, grisly end with this ill-advised spin-off.
