Yes, there was. The movie adaptation of 'Hawaii' aimed to translate the rich narrative and characters of the novel into a visual format. However, as with many adaptations, it might have left out some details or interpreted certain parts differently to fit the cinematic medium.
One funny story was when the missile alert happened, a guy thought it was a prank at first. He was in the middle of a barbecue and just casually said, 'Yeah, right, a missile.' But then when he saw others panicking, he realized it might be real and started running around like a headless chicken. It was kind of comical in a way, how his reaction changed so quickly.
One famous Hawaii ghost story is about the Night Marchers. Legend has it that these are the spirits of ancient Hawaiian warriors. They march at night, and it's said that if you see them while they're on their march and you have any Hawaiian blood in you, it can be a very bad omen. People claim to hear the sound of drums and chanting as they approach. It's a spooky tale that has been passed down through generations in Hawaii.
I'm not sure if there's a specific fanfic where Catherine is pregnant in 'Hawaii Five - 0'. Fanfics can vary greatly, and it would depend on the creativity of the individual fanfic writer.
The story of the Night Marchers is quite scary. Just the thought of seeing the spirits of ancient warriors marching in the night with a menacing air is terrifying. The idea that you can't look at them or make noise or face the consequences is really spooky.
Some Hawaiian folktales can also be considered Hawaii fictions. For example, the stories about Pele, the goddess of volcanoes. These tales are filled with magic and cultural significance, often teaching lessons about respecting nature and the power within it.
