Expanding the World of Superman
The untitled series continues the story of Jimmy Olsen following the events of James Gunn’s Superman. Rather than focusing on traditional superhero action, the show is reportedly being developed as a crime-mystery comedy that follows Jimmy and members of the Daily Planet as they investigate unusual crimes involving supervillains throughout the DC Universe.
Skyler Gisondo will reprise his role as the ambitious Daily Planet photographer, allowing audiences to spend more time with one of the breakout supporting characters introduced in Superman. The series represents another step in DC Studios’ strategy of expanding its shared universe through interconnected television projects.
A Unique Take on the DC Universe
Unlike many previous DC adaptations, the Jimmy Olsen series is expected to lean heavily into comedy and mystery while exploring lesser-known corners of the DC Universe. Reports indicate that each case will introduce Jimmy and his colleagues to different metahuman threats, giving viewers a fresh perspective on life inside James Gunn’s evolving superhero world.
The project has reportedly been developed by American Vandal creators Dan Perrault and Tony Yacenda, who will write, executive produce, and serve as showrunners. Their experience blending comedy with investigative storytelling has fueled excitement about the series’ distinctive tone.
Joining an Expanding Cast
Holland joins a cast that already includes Skyler Gisondo as Jimmy Olsen and Jimmy Tatro, who is set to portray Gorilla Grodd. The inclusion of one of DC Comics’ most iconic villains suggests the series will introduce a variety of colorful characters while maintaining its investigative format.
Although HBO Max has yet to announce a premiere date, production is reportedly expected to begin later this year. As casting continues, fans are eager to learn which additional heroes and villains may appear throughout the show’s first season.

Another Building Block for DC Studios
The Jimmy Olsen series is one of several projects helping shape the future of James Gunn and Peter Safran’s new DC Universe. Following the success of Superman, the franchise continues to expand across film and television with interconnected stories featuring both iconic heroes and supporting characters.
For Mary Holland, the role represents another exciting addition to her growing résumé while introducing her to one of the entertainment industry’s biggest superhero franchises. As production moves forward, fans will be watching closely for more casting announcements and the first official look at the series.
Why Mary Holland Is an Interesting Addition
Mary Holland has built a strong reputation through comedy, improvisation, and character-driven performances in both television and film. Her work in series such as Ghosts and The Big Door Prize, along with appearances in acclaimed comedies, has showcased her ability to balance humor with emotional depth.
That versatility makes her a natural fit for the Jimmy Olsen spinoff, which is expected to combine mystery, workplace comedy, and superhero storytelling. Although details about Sandra remain under wraps, Holland’s casting suggests the series will lean heavily into its comedic elements while still delivering the high-stakes adventures expected from the DC Universe.
DC Studios Continues Expanding Its Shared Universe
The Jimmy Olsen series is another example of DC Studios’ broader strategy to create a connected universe that extends beyond its biggest heroes. Rather than focusing exclusively on Superman or Batman, the new DCU is giving supporting characters the opportunity to headline their own stories and explore different corners of the franchise.
By centering a series on Jimmy Olsen, DC can introduce audiences to new characters, unexpected villains, and fresh storylines while expanding the world established in Superman. The approach also allows viewers to experience the DC Universe from a grounded perspective, with investigative journalism and mystery driving much of the narrative instead of traditional superhero battles.
