Early concept art revealed Cillian Murphy’s potential return to the Tron universe as Sark in the upcoming film Tron: Ares, but the actor ultimately did not reprise his role. Despite the striking design showcasing Murphy’s reimagined character, the project moved forward without him, shifting focus to a new storyline and cast.
Phil Saunders, a film concept artist, shared on ArtStation the early illustration he created at production designer Darren Gilford’s request. Gilford had asked Saunders to produce a quick depiction of Murphy as a modernized Sark to possibly persuade the actor to return as Edward Dillinger Jr., his character from Tron: Legacy. However, Murphy’s involvement never materialized in the final production.
In place of Murphy’s Sark, the movie introduces Julian Dillinger, portrayed by Evan Peters. Julian now leads Dillinger Systems as CEO and faces a new threat when Eve Kim, played by Greta Lee, acquires Kevin Flynn’s permanence code. To handle this challenge, Julian deploys the combat programs Ares (Jared Leto) and Athena (Jodie Turner-Smith) to recover the code.
The Film’s Story Development and Casting Changes
Tron: Ares diverges from returning characters, opting instead for fresh faces and a more streamlined plot. Evan Peters steps into the role of Julian Dillinger, a character responsible for unleashing Ares and Athena in pursuit of Flynn’s code. The narrative centers on cyber warfare within the digital Grid, moving away from the complex mythology that marked earlier entries in the franchise.

Alongside Peters, Jared Leto plays Ares, a rogue AI antagonist, while Greta Lee’s Eve Kim emerges as a critical figure due to her possession of the crucial permanence code. Jodie Turner-Smith rounds out the leads as Athena, a skilled combat program. This new ensemble sets the stage for a dynamic conflict in the evolving digital world of Tron.
Critical Reception Highlights the Film’s Strengths and Weaknesses
Reviews of Tron: Ares focus on its visual appeal, music, and simplified storytelling. Ross Bonaime of Collider praised the film for trimming down the franchise’s dense lore into a more digestible and engaging story. This approach allows the film to maintain momentum without becoming bogged down in overly intricate plot details.
“Tron: Ares isn’t likely to turn Tron into the major franchise Disney has clearly wanted it to be for decades, but it is a sign that the company has a smarter understanding of what these movies need to be: exciting to look at, with a great soundtrack, and with a story that’s dumb fun. Tron: Ares not only achieves that, but finds fun ways to fit in the other installments that make you actually want to see more installments in this world, as opposed to having them forced upon us. Tron: Ares isn’t a killer app, but it is a solid upgrade.” – Ross Bonaime, Collider
While Tron: Ares might not elevate the franchise to blockbuster status, it represents a noticeable improvement in tone and style. The movie balances visual spectacle and a vibrant soundtrack with a more accessible story, aiming for entertainment rather than complexity.
Availability and What the Future Holds for the Tron Franchise
Tron: Ares is now available for streaming on Disney+, making it accessible to long-time fans as well as newcomers. Though Cillian Murphy’s absence changes the project’s dynamic, the film introduces a new chapter in the Tron saga focused on updated characters and fresh conflicts within the Grid.
The shift away from returning legacy characters like Edward Dillinger Jr. suggests the franchise may continue evolving in unexpected directions. If the film’s positive reception persists, Disney could continue exploring this refreshed vision with further sequels or related content, building on the momentum Tron: Ares aims to establish.
