Incredibly, it's been almost 28 years since Pixar released A Bug's Life. The studio's second feature-length movie came three years after Toy Story in 1995 and proved that to the public that the studio was more than a one-trick pony, paving the way for its domination of movie animation in the years to comes.
Despite the movie's huge success (it earned $363.3 million on a budget of $40–120 million), it never got a sequel, despite movies like The Incredibles and Cars getting follow ups. Pixar even joked about the lack of a sequel in the blooper reel at the end of Toy Story 2 in 1999, when Buzz Lightyear ejects Flik and Heimlich from the set.
