Cast, Story Details, Trailer & Everything We Know

There is plenty to be excited about with the new Venture Bros. movie, titled The Venture Bros.: Radiant is The Blood of The Baboon’s Heart, and the most recent news only deepens the hype. Following the unexpected cancelation of The Venture Bros. in the wake of its explosive seventh season, viewers were left with unresolved questions. Thankfully, Adult Swim and Max soon announced a feature-length film, which will serve as a series finale. The show exists simultaneously as a parody of and worthy addition to the genre of boy-adventure sci-fi cartoons, following unethical scientist Dr. Venture, his bodyguard Brock Samson, and teenage sons Dean and Hank Venture.


The Venture Bros. debuted in 2004 and is considered one of the best Adult Swim series programmed around that time. Initially conceived as a send-up of 1960s Hanna-Barbera cartoons, most prominently Jonny Quest, the show has evolved to embody a rich mythos and compelling dramatic world while still maintaining its comedic charm. The Venture Bros. holds the record for the fewest seasons produced of a scripted show per year of continuous production, having seen just seven seasons across its 15 years. The writers used the breaks to develop a dense lore behind the show’s expanding universe of characters, many of whom will return for the Venture Bros. movie.

The Venture Bros. Movie Latest News

The most recent news regarding the Venture Bros. movie is the biggest yet. June 8, 2023, saw the release of the full trailer for The Venture Bros.: Radiant is The Blood of The Baboon Heart. While the trailer delivers comedy and teases some thrilling confrontations, its most exciting aspect is the array of returning characters on display. The Venture Bros. has made a name for itself with the rich, complex world that the series has gradually constructed over its seven seasons, and it’s gratifying to see that several fan-favorite characters will be returning for a final send-off.

The trailer gives away very little in terms of story detail, being so packed with characters that there’s little space left to explore the plot. For an uninitiated viewer, the densely loaded trailer would seem almost impenetrable. It’s a testament to the skillful worldbuilding of writers Christopher McCulloch and Doc Hammer that the busy trailer not only makes sense to fans but succeeds in building considerable anticipation. The trailer drop coincides with news of the film’s release date, which will be in late July 2023.

Production on The Venture Bros.: Radiant is The Blood of The Baboon’s Heart has been quick for a Venture Bros. project. The two-year gap between the film’s announcement and its release date is shorter than the gaps between The Venture Bros. seasons 4 and 5 and between seasons 5 and 6. The Venture Bros. movie will be released on July 21, 2023, on digital and on July 25, 2023, on Blu-ray. It will later stream on Adult Swim and Max.

The Venture Bros. Movie Story Details

Plot details for the Venture Bros. movie seem to promise a mix of new story threads and continuations of lingering questions from the series. A primary storyline in The Venture Bros.: Radiant is The Blood of The Baboon Heart will follow the nationwide manhunt for Hank Venture, who runs away after waking up from a coma in the season 7 finale. The Venture Bros. movie will follow a new antagonist, likely Mantilla (Nina Arianda), as she threatens the worlds of the Ventures, The Monarchs, and the Guild of Calamitous Intent.

Several other plot lines from the series were left unresolved, and the movie is likely to tackle some of the unanswered questions from The Venture Bros. season 7. The final season revealed that Dr. Venture and The Monarch are brothers; the movie will certainly deal with the fallout of this revelation and the effect it has on their dynamic. The identity of Hank and Dean’s mother was also unanswered. However, season 7 saw the Action Man tell Hank that his mother’s name might be Bobbi St. Simone. The Venture Bros. movie lists a character with this name among its cast, making it highly likely that the subplot will be explored.

The Venture Bros. Movie Trailer


The movie’s trailer sheds some light on some of the likely plot developments in The Venture Bros.: Vibrant is The Blood of The Baboon Heart. Dean can be seen seeking out Dr. Orpheus’s help to find Hank, while Dr. Venture is rushing out an untested invention that appears to be a smart speaker mixed with H.E.L.P.eR. There’s a first look at the new character Mantilla, whose introduction hints heavily toward her being a villain. In true Venture Bros. fashion, the trailer also features an obscure callback, as H.E.L.P.eR. is shown using his special hand attachments to cock a shotgun, a reference to a memorable moment from season 1, episode 8.

The full trailer comes after an initial glimpse was provided in April 2023, when Adult Swim released the first clip from the Venture Bros. movie. The scene sees Brock Samson leading a pre-dawn raid in search of Hank, while Dean, Dr. Venture, and General Hunter Gathers watch on. The clip ends just as Samson approaches what appears to be the body of Hank lying behind a dumpster. The scene came as a reassuring first look, affirming that the series’ blend of drama, comedy, and genre pastiche would remain intact for The Venture Bros.: Vibrant is The Blood of The Baboon Heart.
