Chatgpt think it's possible, just takes a ton of work:
Technically, yes, but it would be a massive undertaking. You’d essentially be making a deepfake-style recreation of the entire movie with new actors' faces, voices, and performances while keeping the original pacing, cinematography, and editing intact. Here’s what would be involved:
Face Replacement – You'd need AI deepfake technology or CGI to replace each character’s face with the new actor while maintaining expressions, lighting, and movements.
Voice Replacement – AI voice cloning or ADR (automated dialogue replacement) with the new actors re-recording the lines would be required. The challenge is syncing their voices naturally to the existing scenes.
Performance Matching – Since you're keeping the original movie unchanged in all other ways, the new actors would need to replicate the exact delivery, tone, and style of the original actors. If the new actors' styles differ significantly, the result could feel unnatural.
Legal & Copyright Issues – If done commercially, you'd likely face serious copyright hurdles, as you’d still be using the original film’s cinematography, editing, and score.
AI-Assisted Recreation – Future AI tools might automate this process, making it easier to swap characters in movies without human intervention. But today, it would take an enormous budget and effort.
So, while theoretically possible, it would be more practical to just remake the movie with a new cast rather than attempting a 1:1 actor swap with AI.
Has anyone done this before? Can someone please crowdfund it? I think it would be an amazing thing to experience.
