Corrected entry: At the very end of the movie, look very closely behind the left side of the Flintstones' house. You can very clearly see a telephone pole.
Corrected entry: Near the end, the kids are kidnapped. If Bamm Bamm is so strong, why does he not release himself and Pebbles when they are tied with ropes?
Correction: At best, a character mistake. Would you expect a child that young to have that much presence of mind when he's probably very scared?
Corrected entry: When Fred is walking into the cave where the homeless people live, he is wearing black clothes. But when he is trying to escape from the mad people and is running out of the cave, he has changed to his normal orange/black clothes.
Correction: He took off the black coat when he went in the cave.
Corrected entry: Cliff's plan was to find an idiot, promote him to vice president, frame him for embezzlement, and run off with all the money. So, why did he promote Fred, whom he thinks scored the highest on the exam? Cliff obviously knows nothing about Barney switching Fred's test with his.
Correction: Cliff's plan was to frame the person who got the highest promotion, not an "idiot." The fact that he thought Fred got the highest score is a plus because Fred is not at all intelligent.
Correction: There are evidently some things that run on electricity in the realm of this show though as evidenced by the multiple television broadcasts shown throughout the movie and the fact that Wilma destroys a television set in one scene. The cables for the electricity would need to be run along streets and into houses with the telephone poles.
