Exploring the Collaborative Film Projects of Mckenna Grace and Mason Thames

As of 2026, the primary collaboration between Mckenna Grace and Mason Thames is the feature film Monster Summer (originally titled Boys of Summer). Released in late 2024, this adventure-mystery marked the first time these two prominent young actors shared the screen, anchoring a nostalgic, high-stakes narrative directed by David Henrie.

The pairing of Mckenna Grace and Mason Thames represents a significant intersection of two of the most successful young trajectories in modern Hollywood. While they have built extensive individual filmographies—Grace in blockbuster franchises like Ghostbusters and Thames in breakout hits like The Black Phone—their work together in Monster Summer stands as a definitive moment for fans of the "Amblin-esque" adventure genre. This article examines their shared work, the development of their professional relationship, and the impact of their collaboration on the cinematic landscape.

The Definitive Collaboration: Monster Summer (2024)

The centerpiece of any discussion regarding Mckenna Grace and Mason Thames movies together is undoubtedly Monster Summer. Directed by David Henrie and written by Cornelius Uliano and Bryan Schulz, the film was designed as a throwback to the supernatural adventure films of the 1980s, blending mystery with a coming-of-age emotional core.

Production and Development

The project, initially known under the working title Boys of Summer, began production in late 2021 and early 2022. Filming primarily took place in Southport, North Carolina, which served as the backdrop for the fictional Martha's Vineyard setting. The production sought to capture a specific aesthetic: the sun-drenched, slightly eerie atmosphere of a coastal summer where something hidden lurks beneath the surface.

For Thames, the film was an opportunity to transition from the pure horror of The Black Phone into a more traditional hero role. For Grace, it was another chance to showcase her versatility in a genre she has frequented—mystery and supernatural drama. Their casting was seen as a "power move" by the studio, as both actors had already established significant pull with younger audiences and critics alike.

Plot and Character Dynamics

In Monster Summer, Mason Thames stars as Noah, a young boy whose best friend mysteriously disappears during what was supposed to be a relaxing summer break. Noah suspects that a supernatural force or a hidden predator is responsible, leading him to seek the help of a local retired detective, played by Mel Gibson.

Mckenna Grace plays a pivotal role in the group of friends, providing a character that balances Thames’s more impulsive Noah with grounded intelligence and technical resourcefulness. The chemistry between Grace and Thames was a focal point of the film’s marketing and eventual critical reception. Critics noted that their interactions felt organic, avoiding the clichés of forced teen romance in favor of a high-stakes partnership built on mutual trust and shared danger.

Critical and Commercial Reception

Upon its release, the film was praised for its nostalgic tone and the performances of its young leads. By 2026, Monster Summer has found a permanent home on major streaming platforms, often appearing in "Top 10" lists for family-friendly mystery and adventure. The film's success solidified both Grace and Thames as reliable box-office draws who can carry a narrative that appeals to both children and nostalgic adults.

Mckenna Grace: A Prolific Career Path

To understand the weight of the Grace-Thames collaboration, one must look at the individual stature of Mckenna Grace. By 2026, Grace has transitioned from a child prodigy into a seasoned lead actress and producer.

Early Breakout and Versatility

Grace first gained massive attention for her role in Gifted (2017) alongside Chris Evans. Her ability to handle complex, emotionally demanding roles at a young age led to a string of high-profile "younger version" roles, portraying the child versions of characters played by Brie Larson (Captain Marvel), Margot Robbie (I, Tonya), and Kate Siegel (The Haunting of Hill House).

The Ghostbusters Era

Her most significant commercial impact came with the revival of the Ghostbusters franchise. As Phoebe Spengler in Ghostbusters: Afterlife (2021) and Ghostbusters: Frozen Empire (2024), she became the face of a legacy series. Her performance as the socially awkward but brilliant granddaughter of Egon Spengler was lauded for its nuance. By the time she filmed Monster Summer with Mason Thames, she was already one of the most recognizable faces in the genre.

Artistic Evolution

Beyond acting, Grace has expanded into music and screenwriting. Her involvement in the 2022 film The Bad Seed Returns, which she co-wrote and executive produced, demonstrated a level of industry savvy rarely seen in actors her age. This technical depth influenced her performance in Monster Summer, where she brought a refined sense of pacing and character motivation to her role.

Mason Thames: The Rise of a New Leading Man

While Mckenna Grace had a head start in the industry, Mason Thames’s rise was meteoric following a single, culture-shifting performance.

The Black Phone Impact

Thames’s breakout role in Scott Derrickson’s The Black Phone (2021) established him as a premier talent in the thriller and horror genres. Playing Finney, a boy kidnapped by a serial killer who communicates with past victims via a disconnected phone, Thames displayed a physical and emotional range that caught the attention of major studios.

Broadening the Portfolio

Following The Black Phone, Thames was cast in the TV series Walker and secured the lead in the live-action adaptation of How to Train Your Dragon. His casting in Monster Summer alongside Grace was a strategic move to pair him with another high-caliber young actor, ensuring the film had the acting "muscle" required to stand out in a crowded market.

By 2026, Thames has become known for his "everyman" quality—an ability to play relatable, often vulnerable characters who find extraordinary strength in desperate situations. This made him the perfect foil for Grace’s typically more analytical and sharp-witted characters.

Comparing the Careers of Grace and Thames

While Monster Summer is their primary movie together, comparing their filmographies reveals why they are frequently linked in the minds of casting directors and fans. Both actors have a penchant for "elevated genre" projects—films that use horror, sci-fi, or adventure as a lens to explore deeper themes of family, trauma, and growing up.

The Significance of Their Pairing in Modern Cinema

The collaboration in Monster Summer is more than just a single movie; it represents a shift in how Hollywood utilizes "Gen Z" talent. In previous decades, young stars were often relegated to disposable teen comedies or Disney-style sitcoms. Grace and Thames represent a new breed of young actors who are treated with the same seriousness as adult A-listers.

Technical Skill and Professionalism

Both actors are known for their professional discipline. On the set of Monster Summer, director David Henrie noted that the two leads brought a level of preparation that allowed the production to move more like an adult drama than a children’s adventure. This professionalism is a primary reason why they have both successfully navigated the transition from child stars to adult actors.

Audience Crossover

The "Grace-Thames" fan base overlap is significant. Grace brings in the Ghostbusters and Handmaid’s Tale audience, while Thames brings in the horror-centric and How to Train Your Dragon fans. This synergy helped Monster Summer achieve a wider demographic reach than a typical indie adventure film.

Future Potential: Will They Work Together Again?

As of mid-2026, there are no officially confirmed projects that feature both Mckenna Grace and Mason Thames. However, the industry frequently reunites successful pairings. Given the positive reception of their chemistry in Monster Summer, several factors suggest a future collaboration is likely:

1. Genre Alignment: Both continue to work in the supernatural and thriller spaces.
2. Shared Network: Having worked with directors like David Henrie and being part of the same Hollywood social and professional circles, they are often in the same "shortlist" for upcoming scripts.
3. Fan Demand: Since the 2024 release, "Grace and Thames" has become a popular search query, indicating a market for their reunion.

Industry insiders have speculated about a potential sequel to Monster Summer, given its strong performance on streaming platforms, though no official greenlight has been announced as of this writing.
