In the upcoming sci-fi thriller Mercy, set to release on January 23, 2026, an LAPD detective finds himself in a dire situation. The film's protagonist, played by Chris Pratt, wakes up strapped to an execution chair, on trial for the murder of his wife. He has just 90 minutes to prove his innocence to an advanced AI system known as Judge Maddox, portrayed by Rebecca Ferguson, which is acting as his literal judge, jury, and executioner.
The film's creative team, including director Timur Bekmambetov and producer Charles Roven, recently took the stage at New York Comic Con to discuss their unique approach to filming Mercy. The director noted that the 90-minute runtime was a "great tool" as it forced them to tell the story in real-time, creating a ticking clock scenario within the courtroom setting.
To capture the character's digital life being used as evidence against him, the production team employed a novel filming technique. Pratt's character interacts with a holographic projection of his policing partner, played by Kali Reis, while also facing a barrage of digital screens displaying evidence from his past, including social media posts and video calls. This blend of practical and green screen effects, along with the use of robodogs as cameramen, resulted in a visually striking and immersive experience for the audience.
As the AI element of the story becomes increasingly relevant in today's world, the producers believe Mercy will resonate with audiences, raising questions about the role of technology in the criminal justice system and whether AI can truly be trusted to make impartial decisions.
