Corrected entry: Max (the white and brown dog) has a brown spot on his eye that keeps switching sides throughout the entire movie.
The Secret Life of Pets 2 (2019)
1 corrected entry
Directed by: Chris Renaud, Jonathan del Val
Starring: Kevin Hart, Patton Oswalt, Jenny Slate, Eric Stonestreet
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.
Correction: No error with the spot on his eye at all.
