The Monarch: Legacy of Monsters universe is expanding, with production now underway in Prague on Apple TV+ and Legendary Entertainment’s upcoming Monsterverse spinoff centered on Colonel Lee Shaw.
The project is filming in the Czech Republic under the production title Birdwatcher, which may ultimately serve as a working title. Filming is expected to take place in Prague and elsewhere in Czechia throughout the summer, adding another major international television production to the country’s growing slate.
For fans of Monarch: Legacy of Monsters, the new series promises something considerably different from the original show. The Lee Shaw spinoff is set in 1984 and is expected to blend the Monsterverse’s Titan mythology with the tension and intrigue of a Cold War spy thriller.
For actors and background performers, the production is also notable because local casting activity connected to Birdwatcher has surfaced in Prague.
What Is “Birdwatcher”?
Apple TV+ and Legendary Entertainment have not announced an official title for the Monarch: Legacy of Monsters spinoff, but the production is operating under the name Birdwatcher in the Czech Republic.
The name has appeared across several sources connected to the Czech production.
The project has been registered with the Czech Audiovisual Fund under the Birdwatcher title, while local municipal documentation concerning filming logistics has also reportedly referenced the name.
United Agents, representatives for filmmaker Andy Goddard, describes him as a director and executive producer on an upcoming 1980s Cold War spy thriller titled Birdwatcher, starring Wyatt Russell for Apple TV+ and Legendary Entertainment.
Czech Film Commissioner Pavlína Žipková has also referenced the project as The American Birdwatcher while discussing international productions working in the Czech Republic.
Stillking Films, a prominent Czech production services company, is coordinating local production activities.
Together, these details establish Birdwatcher as the production identity currently being used for the new Monarch: Legacy of Monsters project in Czechia.
Where Is the Monarch: Legacy of Monsters Spinoff Filming?
Production is taking place in Prague and other locations throughout the Czech Republic.
Location filming has taken place in Prague, including the Prague 3 district, with additional locations in central Prague reportedly reserved for the production.
The series is also expected to combine location filming with substantial studio work. That would be unsurprising for a Monsterverse production, where practical sets and locations can be combined with extensive visual effects to create the franchise’s enormous Titans and large-scale action sequences.
Prague offers the production a combination of historic European architecture, experienced local crews, studio infrastructure, and locations capable of doubling for other parts of Europe.
Those qualities are particularly useful for a series set against the international backdrop of the Cold War.
Wyatt Russell Returns as Lee Shaw
Wyatt Russell is returning to the Monsterverse as the younger Colonel Lee Shaw, one of the central characters introduced in Monarch: Legacy of Monsters.
The original Apple TV+ series used two actors to portray Shaw across different periods.
Wyatt Russell played the younger Shaw, while his father, Kurt Russell, portrayed the older version of the character.
The new spinoff will put Wyatt Russell’s version of Lee Shaw at the center of the story.
What Is the Monarch: Legacy of Monsters Spinoff About?
The series is set in 1984, placing Lee Shaw in the middle of the Cold War.
According to details surrounding the project, Shaw embarks on a covert mission behind enemy lines involving a potentially devastating new Titan.
The mission reportedly requires Shaw to prevent the Soviet Union from unleashing the creature against the United States, an event that could dramatically alter the balance of power during the Cold War.
That premise gives the Monsterverse an opportunity to explore territory that is very different from a traditional giant-monster story.
Instead, the production can combine espionage, military operations, international politics, covert missions, and the threat of Titans within the same narrative.
How Will the Spinoff Differ From Monarch: Legacy of Monsters?
Audiences shouldn’t necessarily expect Monarch: Legacy of Monsters recreated with a new setting.
Wyatt Russell has indicated that the Lee Shaw series will occupy a distinctly different genre from Monarch.
Speaking with The Hollywood Reporter, Russell expressed enthusiasm about the scripts and suggested that viewers may be surprised by the direction of the series.
The original Monarch: Legacy of Monsters combined family drama, mystery, multiple timelines, and decades of Monsterverse history.
The Lee Shaw spinoff appears positioned much more directly as an 1980s Cold War espionage thriller.
That could mean covert operations and political intrigue play just as important a role as the Titans themselves.
For the wider Monsterverse, the concept also provides another way to expand the franchise without requiring every television project to follow the same formula.
Who Is Behind the New Monsterverse Series?
The project is being overseen by Joby Harold, who serves as showrunner and is involved in guiding Legendary’s broader Monsterverse television slate for Apple TV+.
Harold’s previous credits include Obi-Wan Kenobi, Transformers: Rise of the Beasts, and John Wick: Chapter 3 – Parabellum.
Andy Goddard is also attached to Birdwatcher as a director and executive producer.
With the series combining the Monsterverse with Cold War espionage, the creative team appears to be taking Lee Shaw’s story in a deliberately different direction from the flagship Monarch series.
Who Is Casting the Monarch: Legacy of Monsters Spinoff?
For actors and background performers interested in the Monarch: Legacy of Monsters spinoff, local casting activity in the Czech Republic is being handled by Casting – Barrandov, s.r.o.
Casting – Barrandov is a Prague-based casting agency that works with actors, extras, and productions filming in the Czech Republic.
The agency has been recruiting performers in connection with Birdwatcher, providing another link between the working production title and the Monsterverse series currently filming in Czechia.
A casting notice connected with the production has sought male performers to portray soldiers, demonstrating that local background casting is taking place alongside principal photography.
It is important to distinguish local casting from principal casting. Casting – Barrandov’s involvement indicates that the agency is handling at least some Czech casting and background performer needs for Birdwatcher. That does not necessarily mean the company is responsible for casting the show’s principal international roles.
At this time, the available information does not establish the individual casting director or casting directors overseeing all principal casting for the series.
Actors interested in appearing in the production should therefore pay close attention to legitimate local casting notices as filming continues.

What Actors Should Know Before Applying
Because Birdwatcher is filming in the Czech Republic, some opportunities may specifically target performers who are already based in Prague or elsewhere in Czechia and who are legally eligible to work locally.
Background casting requirements can also be highly specific.
Productions may search for performers based on age, appearance, costume measurements, availability, language abilities, military experience, special skills, or their ability to match the historical period being portrayed.
Since this story takes place in 1984 and includes military and Cold War elements, background casting could play an important role in creating the period setting.
Performers should always follow the requirements stated in each individual casting notice rather than contacting production companies, cast members, or filmmakers directly.
Prague Continues to Attract Major Film and TV Productions
The Monarch: Legacy of Monsters spinoff joins a growing list of major international productions choosing Prague and the Czech Republic as filming destinations.
Projects working in the country during 2026 have included Martin Scorsese’s What Happens at Night, Apple TV+’s Foundation, Netflix’s The Age of Innocence, and the John le Carré adaptation Legacy of Spies.
The upcoming Dan Brown adaptation The Secret of Secrets has also been slated for production in Prague.
The continued arrival of major studio and streaming projects reinforces the Czech Republic’s reputation as an important European production hub.
For local actors, extras, crew members, and entertainment professionals, that activity can also mean a steady flow of potential production opportunities.
Is There a Release Date for the Monarch: Legacy of Monsters Spinoff?
Apple TV+ has not announced a release date for the Lee Shaw series.
With production underway, additional details about the show’s title, cast, episodes, and eventual premiere are likely to emerge as the project moves further through production and post-production.
Until Apple TV+ or Legendary Entertainment makes an official announcement, Birdwatcher should be treated as the production title associated with the project rather than its confirmed final release title.
