Over the Garden Wall has been a source of magic for viewers, even though its first episode aired on Cartoon Network almost a decade ago.
The show became more popular after the release of the 10th-anniversary stop-motion short in November 2024, which brought interest back to the fairytale-like realm of Unknown. This new short film was created by Patrick McHale, Dan Ojari, and Mikey Please, who together created the vision that gave the series its new life.
It was after the shorts’ premiere that the old and new fans started to talk about the show’s different kinds of charms, the cast, and the characters that made Over the Garden Wall one-of-a-kind.
The miniseries Over the Garden Wall is adored for its comforting autumnal atmosphere, daring storytelling, and the comical troupe of wacky characters that fill the space. One of these characters is Jimmy Brown, who you might remember from the famous Schooltown Follies episode. His character is the love interest of Miss Langtree.
The character’s overwhelming appeal is attributed mainly to the great voice acting that brought him to life. But who is the actor behind Jimmy Brown’s voice in Over the Garden Wall? The actor’s background unveils a lot of talent and an amazing commitment to the art. Let’s dig into it.
Who voices Jimmy Brown in Over the Garden Wall?

In Over the Garden Wall, the character Jimmy Brown is voiced by Thomas Lennon. His voice can be heard most clearly in the third episode titled Schooltown Follies, where Jimmy is characterized as the mild-tempered yet slightly forgetful fiancé of Miss Langtree.
Although his presence is not very significant, Lennon’s perfect comic timing still makes Jimmy a memorable character, and also a contributor to the specific warmth and gentle absurdity of the episode.
Lennon's triumphs in the field of comedy are very broad and diverse. In addition to being an actor, he is also a writer, comedian, and producer whose impact has been felt across the media of television, film, and animation for over thirty years.
His major turning point was The State, MTV's groundbreaking sketch show of the '90s, which completely changed the face of sketch comedy. The series was highly critiqued for its unusual but hilarious humor and creative risk-taking, and Lennon had a great deal to do with it. If you happened to see a part of the series, then you would surely be acquainted with his distinctive mix of sharp intelligence, humor through body language, and total surrender to the most ridiculous situations.
After The State, Lennon was the co-creator and the main actor in Reno 911!, the cult mockumentary about a sheriff’s department with odd characters. Lennon, as Lieutenant Jim Dangle, recognized for his minuscule shorts and perfectly comical deadpan delivery, turned into an icon of comedy. The show’s improvisational method and outrageous characters marked it a classic for adult comedy, and Lennon’s performance of Dangle, with his deadpan face at the most absurd circumstances, secured his status as the performer who could spot humor in any situation.
Meanwhile, acting is not the only area where Lennon has demonstrated his skills. He is also a great screenwriter and producer and has collaborated on writing the biggest Hollywood comedies. He was the co-writer of the Night at the Museum trilogy, Balls of Fury, and Herbie: Fully Loaded, to name a few. The humor that is approachable and ingenious can be found in his scripts, which makes his work accessible to many different people.
The same can be said for his voice acting. Lennon has given us such colorful character portrayals as Pinter in Planet Sheen and has never failed to infuse his personality into the animated roles. One can hardly tell that the same actor is behind the voice of a spaced-out scientist, a docile sidekick, a clumsy suitor, and that all of them are practically stamped with the signature of Lennon’s comic talents.
Lennon has been a part of various TV comedies with guest and recurring roles throughout his whole career: The Hotwives, Crash Test, and so on. Thomas Lennon is one of the few actors who can do everything: leading a project, supporting a cast, writing behind the scenes, or providing a voice.
