At one hour and fifty-eight minutes, this is not only the longest Pixar film to date, but was also the longest computer-animated feature film to date, until it was beaten by Spider-Man: Across the Spider-Verse (2023).
Writer and director Brad Bird had stated over the years that he would only do a sequel to हम हैं लाजवाब (2004) if he could come up with a story that was just as good as, or better than, its predecessor. The idea of Bob (Mr. Incredible) becoming a stay-at-home dad, while Helen (Elastigirl) becomes the breadwinner was there from the beginning, but it took several years for Bird to come up with the perfect story around which to write this idea.
Instead of this movie being released on June 21, 2019, Pixar swapped release dates with Toy Story 4 (2019), as the film was being completed ahead of schedule, while the other was lagging in production, which was initially going to be released on June 15, 2018.
For this movie, Huck Milner took over voicing Dash, as the character's original voice actor Spencer Fox had deepened since हम हैं लाजवाब (2004).
Some of Jack-Jack's voice uses archival recordings.
