Edgar: Why don't I... [struggles with the brush before applying paint to the canvas]
Raz: Wow. See? Sometimes you just have to... you painted a bullfight over the doctor's face. Why a bullfight? Huh? Edgar, why do you—
Edgar: EVERY TIME! Every time it's the same! The matador! The bull! How I despise you both! But my hands... my hands won't let you go. [throws away and replaces the canvas] That is why I am here, chained more ways than you can see.
Raz: A prisoner of art.
Edgar: A prisoner of art.
When trying to create something, anything, being inspired is the first step. With a good idea in mind, it becomes much easier to make that art a reality. However, for some, finding inspiration isn't necessary, because they already know what they'll make.
They know, because they've made it before, and they'll make it again, and they'll keep on making it.
The subject and medium can vary wildly, as it all depends on the person behind these creations. Maybe Alice is obsessed with painting pictures of bats, and so she fills up her studio with nothing but. Maybe Bob can't stop drawing flowers, even after he's run through every flower species he knows of. Maybe Charlie only takes photos of his dog, and refuses to waste camera-roll space on anything else.
What can also vary is the reason behind the obsession. The easiest explanation is that the artist just has an extreme interest in one thing and a lack of interest in anything else. The darker explanations can be as mundane as mental illness to being outright supernatural in origin; this is especially likely when the character in question isn't even an artist, but is just compelled to repeatedly create similar works after an encounter with the unknown. Another reason could be Author Appeal.
For extra fun, this can be played in two ways. When Played for Laughs, the obsession will be downright silly, and it'll just be a funny quirk. Played for Drama, and the situation can be almost a look into the character's psyche, or the symptom of a much larger, much darker obsession, bordering on or outright being Played for Horror.
To see if someone fits, common signs to look out for are that the artist's room, studio, or what-have-you is filled with art of this particular subject, in-universe acknowledgement about the obsession, or even a scene of just watching them create similar works over and over again. A person who just happens to specialize in one specific field, like a carpenter who only makes chairs, doesn't fit unless it's clear their field is based on an obsession.

- In Fantastic Mr. Fox, all of Mrs. Fox's paintings involve stormy weather (usually lightning, but in one instance a tornado).
- In Tangled, all of Rapunzel's paintings have the sun on them somewhere. This could have something to do with either the lanterns that get sent up on her birthday, the fact that she was the lost princess of a kingdom who use a sun as their symbol, the fact that her powers come from a flower that was powered with "a drop of sun", or a combination.
- 50 First Dates: Lucy is an artist whose ability to create new memories was damaged in a terrible accident — with her anterograde amnesia, she wakes up every day believing it's Sunday, October 13th.

Jade: It's really a lettera d'amore to The Nanny. But, more importantly, it's a reaction to all of our experiences surrounding The Nanny.
- In Superbad, Seth has an obsession with drawing penises. Penises with blades and spikes, penises dressed as clowns, penises melting like Dali art, penises on cars and on fire... the art is of a pretty good quality, mind, but understandably his parents and art teacher find it pretty disturbing and Seth starts the film being forced to go to therapy. He is also not on speaking terms with a former childhood sweetheart because he believes she is he one who told his parents about his art.

- The Fast Show: Johnny Nice Painter combines this with Madness Mantra: while he's perfectly able to paint other things, any mention of the word "black" in his presense causes him to start smearing black paint over everything he's painted up until that point while rambling incoherrently about negative things.
- In Psychonauts, velvet painter Edgar Teglee suffers from an Ambiguous Disorder that gives him a Hair-Trigger Temper and an odd obsession in painting bulls and bullfighters and nothing else. He is assigned by his "psychiatrist" Dr. Loboto to paint his portrait as a part of his treatment, but every time he tries, his psychosis gets in the way, leaving him literally chained to the floor of the abandoned asylum. When Raz uses Sasha's mind-portal to enter his mind (portrayed as a Mexican villa painted on black velvet), he discovers on the surface that it involves his wife Lampita getting seduced by the bullfighter Dingo and ultimately leaving Edgar to be with him. Edgar was devastated by this and was driven mad with heartbreak, painting nothing but bullfights to symbolize his anguish. Or at least, that's the romanticized version, as what really happened was that his high school girlfriend was stolen away by a male cheerleader, breaking his fighting spirit and causing his friends on the wrestling team to abandon him, leaving him nowhere else to turn but the art lab.
