Despicable Me 3 (2017)

Plot hole: Bratt's bubble gum is strong enough to withstand projectiles like bullets, lasers, and even strong enough to carry a tanker into the sky but can't withstand Gru's body weight when he crashes into it before "happy birthday Dan".

Plot hole: After the car is destroyed, Gru is knocked unconscious and Dru enters Balthazar Bratt's robot to destroy the robot's core from the inside. Once Gru wakes up, Balthazar attempts to kill him with the robot's laser and Dru destroys the core causing the robot to collapse. Gru then yells out "Dru!" and runs over to the wreckage of the robot to try and find him. The problem with this is that since Gru was knocked unconscious before Dru entered the robot, and Gru knew nothing of Dru's plan to disable the robot's core, there is no way for him to know that Dru was inside the robot.

Casual Person

Other mistake: When Clive turns the music tape to change side, he puts it in the wrong way. (00:02:20)

Trivia: When the beach-goers panic on seeing the appearance of Balthazar Bratt's robot, you can hear the Wilhelm scream.

Trivia: Due to Elsie Fisher getting too old to voice Agnes, Nev Scharrel was chosen to replace her.

Gru's Mom: Shortly after you and your brother were born, your father and I divorced, and we each took one son. Obviously, I got second pick.

Lucy Wilde: Agents Grucy are closing fast!
Gru: Yes! Wait, whaa? What did you call us?
Lucy Wilde: Grucy. You know, Gru and Lucy mushed together - Grucy.
Gru: I like it, but not a lot. I don't like it.

Silas: Wait, that's not a monster! That's a man wearing shoulder pads. There's only one supervillain whose fashion sense is quite dead dated... Balthazar Bratt! I want every agent on this scene immediately.

Question: Between the first two films Gru had hundreds of minions but in this film he's barely got a handful left. What happened to the rest of them?
