10 Worst Movie Mistakes Of 2021 (So Far)

In Luca, the titular sea monster discovers he automatically takes the form of a human if he leaves the water. Curious about the surface world, he explores a nearby village and befriends another sea monster posing as a human called Alberto. When Alberto tells him about a scooter called a Vespa, Luca enters a triathlon, hoping to purchase the vehicle with the prize money.

At the very end of the triathlon, which is a cycling race, the children get exposed to water, revealing their true forms to the locals. Fortunately, the people accept the boys for who they are when they realise they pose no threat. Not only that, they declare them the winners of the contest when the judge notices they were the first to cross the finishing line.

However, this uplifting moment is tainted when you notice the bicycle seems to magically moves without explanation. When the judge inspects the bike, we can see it's barely over the finishing line. But when the judge presents the boys with their trophy a moment later, the bike has mysterious shifted 10ft away from its original spot.
