Henry Cavill’s Mustache Protocol Turns His Justice League Controversy Into a Game
Remember when Henry Cavill’s mustache became one of Hollywood’s biggest memes? Well, the actor has finally turned the whole situation into a video game.
For those unfamiliar, Cavill had grown a mustache for Mission: Impossible – Fallout while also being needed for Justice League reshoots. Since he couldn’t shave it, the mustache had to be digitally removed from his Superman scenes, resulting in some rather questionable CGI.
Mustache Protocol takes that controversy and runs with it.
Players control a pixel-art version of Cavill, who must stop a rogue CGI agent from erasing every mustache on the planet. The game features three side-scrolling levels where players jump, fight enemies, and collect power-ups.
Some of the game’s highlights include:
- Mustache-comb sword: Cavill’s character fights enemies using an oversized comb.
- Steak power-ups: Eating steaks bulks up the character and unlocks powerful attacks.
- Arm Reload: A special attack inspired by Cavill’s famous arm-reloading move from Mission: Impossible – Fallout.
- Personal Easter eggs: Cavill’s dogs, Kal and Baggins, make appearances.
- Batman reference: There’s even a nod to Ben Affleck’s Batman, according to players who discovered the Easter egg.
Early impressions have been surprisingly positive. Digital Trends described the game as a fun, silly retro experience, although its relatively simple gameplay means players shouldn’t expect a lengthy adventure.
Mustache Protocol Was Created Using Google’s AI Tools
Interestingly, Cavill developed Mustache Protocol in collaboration with Google using the company’s Googlebook laptop and its built-in AI tools.
Google documented the process in a three-part behind-the-scenes series, showing how Cavill turned his ideas into a playable game.
The tools involved included:
- Antigravity: Helped build gameplay mechanics, visuals, and level layouts.
- Rambler: Converted spoken ideas into usable prompts and instructions.
- Magic Pointer: Helped create and refine visual elements.
- BandLab: Assisted with creating the game’s soundtrack.
The project also serves as a demonstration of Google’s AI-powered development tools. While some observers have expressed reservations about the use of generative AI in game development, early reviews have praised the finished game for its humor and accessibility.
Playing Mustache Protocol Helps Raise $500,000 for Men’s Health
Beyond the jokes and memes, Mustache Protocol has a charitable purpose.
Google has partnered with Movember, an organization dedicated to improving men’s health, and pledged to donate $11 for every game played between November 11 and November 30, 2026, up to a maximum of $500,000.
The donations will support initiatives focused on:
- Men’s mental health
- Suicide prevention
- Prostate cancer
- Testicular cancer
Cavill previously described the project as a “fun game for a serious problem,” highlighting the importance of the campaign.
