• Tom Cruise as Ethan Hunt: The legendary IMF agent, known for his relentless pursuit of justice and performing his own jaw-dropping, near-impossible stunts. Cruise has been the face of the franchise since 1996, and The Final Reckoning is set to be the culmination of his character's journey against The Entity, which threatens to weaponize truth and control the world.
• Ving Rhames as Luther Stickell: The only actor besides Tom Cruise to appear in every Mission: Impossible film. Luther is the team's master computer hacker and technical specialist—the 'brains' of the operation. His role is critical, as his deep understanding of technology makes him both the best defense and the greatest target against an AI enemy.
• Simon Pegg as Benji Dunn: The comic relief and indispensable field agent. Benji has evolved from a simple tech support operator to a fully-fledged IMF agent, providing technical support, comic timing, and often finding himself in the thick of the action alongside Ethan.
• Hayley Atwell as Grace: Introduced in Dead Reckoning Part One as a highly skilled, morally ambiguous thief. Grace has now been recruited into the IMF, and her journey from reluctant accomplice to a full-fledged agent is a central focus. Her character brings a fresh, dynamic energy to the team.
• Vanessa Kirby as Alanna Mitsopolis / The White Widow: The enigmatic, high-level black market broker who operates in the grey area between ally and adversary. As the daughter of the original 'Max' from the first film, her network and resources are crucial to Hunt's mission, though her true allegiance remains a constant question.
• Henry Czerny as Eugene Kittridge: The former IMF Director, who hasn't been seen since the original 1996 film, made a shocking return in Dead Reckoning Part One. Now a high-ranking official, Kittridge represents the institutional authority that is often at odds with Hunt's rogue methods, making him a complex figure of power and mistrust.
• Rebecca Ferguson as Ilsa Faust: The former MI6 agent and a formidable ally who has been a mainstay since Rogue Nation. Her fate at the end of Part One ensures her presence, or the memory of it, will heavily influence Ethan's actions in the final chapter.

New Faces and Shocking Returns: The Final Reckoning Ensemble

Director Christopher McQuarrie has a knack for bringing in A-list talent and deep-cut franchise characters to elevate the stakes. The Final Reckoning continues this tradition, introducing several high-profile actors in key roles and confirming a fan-favorite return that spans three decades.

The New Major Players

The new additions to the cast are set to play significant roles, mostly within the governmental and adversarial structures that Hunt must navigate.

• Hannah Waddingham: Known globally for her role in Ted Lasso, Waddingham joins the cast in an undisclosed role that is speculated to be a powerful, high-ranking government or intelligence official. Her casting adds significant gravitas to the film's political landscape.
• Nick Offerman as Sydney: The Parks and Recreation star is confirmed in the role of Sydney, a figure likely connected to the military or intelligence community. Offerman's presence suggests a character with dry wit and considerable authority.
• Holt McCallany: A veteran actor known for his intense, authoritative roles in shows like Mindhunter. McCallany is expected to play a high-ranking government or military figure who will likely be in pursuit of, or in conflict with, Ethan Hunt.
• Janet McTeer: The celebrated actress joins the ensemble in a role that is yet to be fully revealed, but given her pedigree, she is expected to be a major player in the global power struggle over The Entity.
• Tramell Tillman: Known for his work on Severance, Tillman is another new addition whose role is being kept under wraps, suggesting a pivotal character in the narrative's unfolding.

The Adversaries and Their Enforcers

The primary antagonist remains The Entity, an all-knowing, sentient AI. However, the human agents working on its behalf are what make the threat tangible and deadly.

• Esai Morales as Gabriel: The main human antagonist and Ethan Hunt's dark past. Gabriel is a charismatic, nihilistic terrorist who acts as the primary disciple and enforcer of The Entity, believing the chaos it brings is necessary. His history with Ethan makes their confrontation deeply personal.
• Pom Klementieff as Paris: The ruthless, psychopathic assassin who works for Gabriel. Her character is a force of pure chaos, providing some of the most memorable and brutal action sequences. Having survived her encounter in Part One, her return promises more high-octane violence.
• Shea Whigham as Jasper Briggs: The dedicated and relentless CIA agent tasked with hunting down Ethan Hunt. Briggs is not a villain, but a professional obstacle, representing the government's attempts to contain the global threat through conventional means.
• Greg Tarzan Davis as Degas: Briggs' partner, also a CIA agent. Their ongoing pursuit of Hunt and his team provides a constant, high-stakes complication.

The Deep-Cut 1996 Return

In one of the most surprising and unique casting announcements, The Final Reckoning will feature a character not seen since the original 1996 film, a detail that adds immense topical authority to the franchise's conclusion.

• Rolf Saxon as William Donloe: Donloe was the jinxed CIA analyst from the first film, framed by Jim Phelps and arrested after the Langley mission went sideways. His return is a deep-cut nod to the franchise's origins and suggests that the final mission will tie up loose ends from the very beginning of Ethan Hunt's career, potentially involving the fallout from the original IMF team's demise.

The Legacy of the Mission: Impossible Cast: A Look at the Legends

The longevity of the Mission: Impossible franchise is built on the shoulders of its main cast, who have committed decades to these roles. Their filmographies are as impressive as their on-screen chemistry.

Tom Cruise (Ethan Hunt) - The Perpetual Action Star

Born in Syracuse, New York, in 1962, Tom Cruise is one of the highest-grossing box office stars of all time. His career is defined by his commitment to practical stunts and his intense persona. Outside of the IMF, his most iconic roles include Pete 'Maverick' Mitchell in the Top Gun franchise, Frank T.J. Mackey in Magnolia, and the titular character in Jerry Maguire, the latter two earning him Oscar nominations. He has been the driving creative and physical force behind the Mission: Impossible franchise, defining the modern action hero.

Ving Rhames (Luther Stickell) - The Unbreakable Constant

Ving Rhames (born 1959) is a commanding presence in Hollywood, with a career spanning film, television, and theatre. His role as Luther Stickell is his most enduring, but his filmography boasts other memorable performances, including Marsellus Wallace in Quentin Tarantino's seminal Pulp Fiction. Rhames' character is the emotional anchor of the IMF team, providing not just technical wizardry but a deep, unwavering loyalty to Ethan Hunt.

Simon Pegg (Benji Dunn) - The Heart of the Team

The British actor, comedian, and writer (born 1970) is a celebrated figure in the 'Cornetto Trilogy' (Shaun of the Dead, Hot Fuzz, The World's End). Pegg also plays Scotty in the rebooted Star Trek film series, making him a fixture in two major sci-fi/action franchises. His transition from a purely comedic actor to a capable, yet still hilarious, action hero in the Mission: Impossible films is a highlight of the series' evolution.

Hayley Atwell (Grace) - The New Era of IMF

Hayley Atwell (born 1982) is an English-American actress who first gained international fame as Peggy Carter in the Marvel Cinematic Universe, starring in Captain America: The First Avenger and the spin-off series Agent Carter. Her introduction as Grace in Dead Reckoning Part One instantly established her as a major new player in the Mission: Impossible world. Atwell's blend of vulnerability, sharp wit, and physical capability makes her the perfect foil and partner for Ethan Hunt.

The combined talent of this cast, from the seasoned veterans like Cruise and Rhames to the compelling newcomers like Atwell and Waddingham, ensures that Mission: Impossible – The Final Reckoning will deliver a cinematic event worthy of the franchise's legacy. The stage is set for a dramatic, action-packed conclusion where every character's decision will determine the fate of the world.
