Other mistake: When Elastigirl is chasing the high-speed train, as she is in the middle of making her second final jump to reach the train, if one were to look closely, the train actually drives right past her before she lands. (00:31:40)
RassdytContinuity mistake: At the end of The Incredibles, when the Underminer shows up, the Parr family don their masks but are still in their civilian clothes, though Bob is about to take off his shirt. At the beginning of Incredibles 2, in the flashback, as soon as the Underminer appears, they appear in their super suits. Also, the Underminer leaves out "I hereby declare war on peace and happiness! Soon all will tremble before me!" (02:00:00)
Phillip SealsFactual error: When Elastigirl receives her new bike she discovers it's electric. Later, when she is rescuing the train, the bike hits a mountain and is destroyed in a fireball. What is making the fireball? It's electric so there is no gasoline/diesel to make a fireball, and a lithium explosion doesn't look like that. (00:33:30)
Sanguis
Continuity mistake: After the old lady thanks Dash for saving her from getting crushed by the flung blue vehicle, that vehicle suddenly has been moved slightly to the left from its original landing spot. Also, another wrecked light blue vehicle was visible as the aforementioned blue vehicle hit the ground, after the old lady thanks Dash, it has suddenly been replaced by a white wrecked vehicle instead. (00:05:45)
RassdytContinuity mistake: Bob has lost a lot of sleep and looks dead tired when he's apologizing to his daughter. He's got noticeable five o'clock shadow around his chin and mouth. He falls asleep, and then later he is woken up and Violet informs him he has slept for 17 hours. But now Bob seems clean shaven, or at least no longer has the stubble.
Quantom X
Other mistake: Violet's date with Tony was on a Friday evening. But the next morning, Mr Incredible sends his kids to school.
Answer: I've only seen the movie once in theaters, but I've viewed both DVD and Blu Ray openings on YouTube and didn't see it included, but you can find it if you search "the incredibles 2 theater opening." If it has or ever does air on TV, I don't think you'd see it there.
