The Secret Life of Pets 2 (2019)

Factual error: With a number of flowers blooming, the movie appears take place in spring. There are many scenes of central park with flowering trees and shrubs in full bloom. However, the yellow blooming shrubs called forsythia do not bloom at the same time as the flowering cherry trees. Forsythias bloom about a month earlier than cherries and are usually the first items to bloom in spring.

Continuity mistake: Max jumps onto the circus train just as it is going into a tunnel. While he and Snowball are subsequently fighting the wolves in the driver's cabin, you can see through the windows from the lights that the train is still all the time inside the tunnel. Next, when the driver stops the train and immediately everybody gets out, they are in an open landscape.

Trivia: When a rabbit thug crashes through the last window during Snowball's superhero daydream, he yells a Wilhelm scream.

Trivia: Patton Oswalt replaced Louis CK as Max after Louis CK's sexual misconduct.

Trivia: This is Harrison Ford's first animated voice role in his career.
