There was ambiguity over the series’ greenlight status, with Deadline noting HBO Max had not officially greenlit it and HBO Max declined to comment, while producer Peter Safran hinted filming would occur this year.
Mary Holland has been cast as Sandra, the female lead in DC Studios' untitled Jimmy Olsen spinoff series at HBO Max, according to Empire and Coming Soon. She joins Skyler Gisondo as Jimmy Olsen and Jimmy Tatro as Gorilla Grodd in what is shaping up to be one of the stranger entries in the DC Universe.
The show is described as a true-crime mockumentary in which Olsen hosts investigations into DC villains. Season one puts Gorilla Grodd — a hyper-intelligent telepathic ape — at the center as the main antagonist. James Gunn and Peter Safran are among the executive producers, with the series headed by creators Tony Yacenda and Dan Perrault.
Who Is Mary Holland and Why She Fits This Show
Holland is best known as a comedy specialist. She has a recurring role on the CBS sitcom Ghosts and appears in Netflix's Little House on the Prairie reboot, Head Topics reported. She also trained at the Upright Citizens Brigade, a well-known improv comedy school. That background makes her a natural fit for a series built around mockumentary humor.
Her earlier film credit, Happiest Season, also put her on Hollywood's radar, according to Empire. The casting signals that DC Studios is leaning hard into comedy for this project, pairing trained improvisers with a format that rewards quick, dry wit.
Gorilla Grodd: A 1959 Villain Gets a Mockumentary Moment
Gorilla Grodd was created in 1959 by writer John Broome and artist Carmine Infantino. He is a telepathic, hyper-intelligent ape and one of DC's most unusual villains. Jimmy Tatro, known for comedic roles, will voice and portray the character in Season one, per Cosmic Book News.
The choice to center the first season on Grodd is a bold one. It signals the show wants to be genuinely weird. Insiders describe it as a 'weird superhero' concept — part behind-the-scenes format, part villain showcase, all wrapped in a documentary style, according to Coming Soon.
No Official Greenlight Yet — but Filming May Start This Year
Here is the catch: the show may not be officially greenlit yet. Cosmic Book News noted that HBO Max declined to comment on the deal and has not formally greenlit the series. DC Studios also did not confirm Holland's casting.
Despite that ambiguity, producer Peter Safran has hinted that filming could begin later this year. The project appears to be moving forward in practice, even if the official announcement has not come. AOL and multiple outlets confirmed the casting is being treated as a done deal by insiders.
How This Series Fits Into Gunn's Broader DCU Rebuild
The Jimmy Olsen spinoff is part of a larger effort by James Gunn and Peter Safran to rebuild the DC Universe from the ground up. HBO Max is the platform of choice for DCU television projects. The mockumentary format is a deliberate departure — superhero shows rarely look or feel like this.
By blending comedy credentials, cult DC characters, and a documentary tone, the project aims to carve out its own lane. Empire described it as a 'radical departure for superhero fare.' If it lands, it could open the door to more unconventional DCU storytelling on streaming.
