For years, science fiction has warned us about artificial intelligence taking over the world. But in the entertainment industry, a different kind of takeover is happening right now. Many film enthusiasts are asking: Are movies actually using generative AI in real life? The short answer is a resounding yes. From adjusting actor vocals to recreating late stars and flawless language dubbing, movies using generative AI are no longer a futuristic concept—they are already playing in theaters near you.
While some filmmakers use these tools secretly to avoid public backlash, others are openly embracing them to push creative boundaries. Let’s dive deep into how the film industry is actually utilizing this technology today.
The Shift from CGI to Generative AI
Historically, Hollywood relied on Computer-Generated Imagery (CGI) and traditional VFX to create the impossible. However, these methods are incredibly time-consuming and expensive. Generative AI has changed the game by allowing computers to “create” new content—including video, audio, and images—based on massive datasets. This is why we are seeing more and more mainstream movies using generative AI to cut costs and accelerate post-production.
Instead of manually animating every frame, filmmakers can now use AI models to generate realistic textures, clone voices, and even alter facial expressions in post-production. According to a recent survey on Generative AI for Film Creation, the adoption of AI-generated video and voiceovers has skyrocketed among independent and mainstream creators alike. This shift is redefining the entire filmmaking workflow, from pre-production scriptwriting to post-production sound mixing.
5 Shocking Movies Using Generative AI in Real Life
To understand how deep this technology has penetrated the industry, let’s look at five real-world examples of major movies using generative AI in their production and marketing pipelines.
1. Emilia Pérez: Tuning the Perfect Pitch
The critically acclaimed musical Emilia Pérez (2024) made waves at the Cannes Film Festival, but few realized it featured a subtle touch of generative AI. Sound mixer Cyril Holtz revealed that the production team used the AI voice-cloning software Respeecher. Lead actress Karla Sofía Gascón struggled to hit some of the higher notes required for her musical numbers. Instead of replacing her with a traditional vocal double, the team used AI to adjust her performance, blending her natural voice with synthesized tones to hit the perfect register. This is a prime example of how modern movies using generative AI can enhance a performance without losing the actor’s original soul.
2. The Brutalist: Perfecting Dialogue and Architecture
Directed by Brady Corbet, The Brutalist is another major film that leveraged Respeecher in post-production. The film’s editor, Dávid Jancsó, who is a native Hungarian, used his own voice as a source for the AI tool to refine and improve the Hungarian dialogue spoken by the actors. This allowed the sound team to adjust vowels and letters to ensure perfect pronunciation and cultural authenticity. Furthermore, the production team utilized generative AI tools to help design the complex architectural plans for the protagonist, László Tóth, showcasing AI’s utility in physical set design.
3. Civil War: AI-Generated Marketing Controversy
Alex Garland’s 2024 dystopian thriller Civil War took a different, more controversial approach to AI. Rather than using AI in the film itself, the studio behind it, A24, used generative AI to create a series of promotional posters. These posters depicted post-apocalyptic scenes in major U.S. cities. However, the campaign faced immediate backlash from fans who noticed classic AI “hallucinations”—such as Chicago’s Marina Towers placed on opposite sides of the river and a car with three doors. While most movies using generative AI focus on on-screen effects, A24’s experiment showed the risks of using it for marketing.
4. Watch The Skies: Flawless AI Dubbing
One of the biggest hurdles for international cinema is language dubbing, which often looks awkward due to mismatched lip movements. The Swedish sci-fi adventure Watch The Skies solved this issue using AI technology developed by the firm Flawless. To prepare the film for English-speaking audiences, the software digitally altered the actors’ mouth movements and facial expressions to perfectly sync with the English voiceover tracks. As more international movies using generative AI adopt this technology, the barrier of language in global cinema will completely dissolve.
5. As Deep As The Grave: Recreating Val Kilmer
Perhaps the most emotional use of generative AI in recent cinema involves the late actor Val Kilmer. In the upcoming period drama As Deep As The Grave, AI and deepfake technology were used to recreate Kilmer’s likeness and synthesize his voice to portray the character Father Fintan. With the full consent and cooperation of Kilmer’s family, the filmmakers blended footage captured before his passing with generative AI to complete his final performance. This project represents a new frontier for movies using generative AI, where technology acts as a bridge to preserve cinematic history.
The Legal and Ethical Landscape of AI in Film
The rapid integration of AI has not come without friction. The Hollywood strikes of recent years highlighted actors’ and writers’ fears of being replaced by digital replicas. In response, the industry is moving toward structured regulation. For instance, the German AI Annex collective bargaining agreement established a clear framework for consent-based licensing and remuneration when using generative AI for actors.
As we move forward, the consensus is clear: AI should be used as a tool to assist human creativity, not replace it. Ethical guidelines and licensing agreements will be crucial in ensuring that artists are fairly compensated and respected.
The Future of AI in Filmmaking
Are we going to see fully AI-generated feature films in theaters soon? While indie creators are experimenting with short films, major Hollywood studios are focusing on hybrid workflows. AI will continue to streamline tedious tasks like rotoscoping, color grading, and dialogue clean-up, allowing filmmakers to focus on storytelling.

Conclusion
The question is no longer if movies are using generative AI, but how creatively they can apply it. From the vocal enhancements in Emilia Pérez to the visual dubbing in Watch The Skies, generative AI is actively reshaping the cinematic experience. Ultimately, movies using generative AI are proving that technology is not here to destroy art, but to expand its possibilities. As long as filmmakers balance technological innovation with ethical responsibility, the future of cinema looks incredibly exciting.
