No, it's not appropriate. Writing sexual fanfiction about a real person is an invasion of their privacy and can be considered disrespectful. Fanfiction should focus on the fictional aspects of a character or story, not on real - life individuals in a sexual context.
You can start by looking on fanfiction websites like Archive of Our Own (AO3). It has a large collection of fan - created works, including many about Jake Gyllenhaal.
There are fanfictions that focus on his movie characters' backstories. For example, if he played a detective in a movie, the fanfiction could expand on what made that character become a detective in the first place. Another popular type is time - travel stories where his character from one movie gets transported to another movie's setting.
You could write about his characters in alternative universes. Such as if his character from a period drama was transported to modern times and how he would adapt. It allows for creativity while still respecting the actor and his work.
Well, Maggie Gyllenhaal in 'Stranger than Fiction' plays an important part. Her character often acts as a catalyst for the protagonist's self - discovery. She has great on - screen chemistry with the other actors, which makes the interactions in the movie feel real and engaging. This, in turn, enhances the movie - going experience for the audience.
I haven't come across any reports stating that Jake Tapper is penning a novel. His focus seems to be on his journalistic endeavors, such as reporting the news, conducting interviews, and providing analysis. However, it's not impossible for him to venture into novel - writing in the future, but for now, there's no indication of it.
