TV legend Bryan Fullerknown for his cult classics “Pushing Daisies” and “Hannibal,” just earned an Independent Spirit Award nomination for first feature. It’s somehow a surprise that the well-known creator just directed his first movie, after spending almost three decades working in television on series like “Dead Like Me” and “American Gods.” Now he turns to the world of indie film, reuniting with actor Mads Mikkelsenhis Hannibal Lecter, on the dark fairy tale “Dust Bunny.”

Fuller has a thing for idioms, extending them to their most extreme ends (e.g., “pushing daisies”), and so in “Dust Bunny,” he imagines what those bits of fluff could be if our nightmares came to life. He also posits an outlandish notion: What if a kid hired an assassin to kill the monster under her bed?

Aurora (Sophie Sloan) is an imaginative young girl who hears things that roar and scream in the night. The dust bunny under her bed is a ravenous, monstrous thing.

When her parents go missing, she’s convinced they’ve been eaten by the monster bunny, and seeks out the services of an “intriguing neighbor” (Mikkelsen, that’s how he’s credited) whom she has seen vanquishing dragons in the alley outside. With a fee that she purloins from a church collection plate, she implores him for help and he agrees, as he learns about this young girl’s challenging childhood.

At first, “Dust Bunny” feels a little light, the story skittering across its densely designed surface, with very little dialogue in the first half. But it grows and grows, bits and pieces accumulating as Fuller reveals this strange, heightened world.

We meet Intriguing Neighbor’s handler, Laverne (Sigourney Weaver), revealing the larger Wickian world of killers that he inhabits.Weaver chomps through her scenes like the monster bunny chomps through the floorboards — literally, as she consumes charcuterie, dumplings and “suckling pig tea sandwiches” with gusto. Some monsters grin at us from across the table.

The film is essentially “Leon: The Professional” meets “Amélie” (one of Fuller’s favorite films), but with his distinct wit and flair. That style also means that “Dust Bunny” is quite fussy and mannered and if you don’t buy in on the film’s arch humor and stylized world, you’re liable to bounce right off of it.

As Fuller opens the world up, revealing a sly FBI agent (Sheila Atim) and baddies (David Dastmalchian, Rebecca Henderson), the plot becomes intriguing beyond its unwieldy childhood-trauma metaphor, but there’s also not quite enough embroidered on this tapestry. It feels shallow, not fleshed out.

Fuller demonstrates a strong command over his visual domain but the pat allegory he presents about the monsters with whom we have to learn to live feels a bit muddled. Sloan and Mikkelsen are terrific together, but you feel that there is much they could have sunk their teeth into here, and perhaps the limits of the tale reveal the limits of the budget, carefully wallpapered over with opulent production design — explosions of patterns and color crafted by Jeremy Reed, captured with shadowy but lush cinematography by Nicole Hirsch Whitaker.

It’s a first feature that feels like one — a bit of a surprise from someone so experienced. But the project has Fuller’s signature style, even if it doesn’t add up to much than a neat kiddie-centric hard-R genre exercise.
