Story Highlights
- Spider-Man actor Tom Holland experimented with a controversial dehydration technique to enhance muscle definition for a shirtless scene
- The method, commonly used by bodybuilders before competition, involves strategic water restriction to reduce subcutaneous water retention
- Holland reported that the approach left him irritable rather than achieving the desired physical results
- The 30-year-old actor was filming a bathhouse sequence for Spider-Man: Brand New Day with actress Florence Pugh
What Happened
During production of the latest Spider-Man installment, titled Spider-Man: Brand New Day, actor Tom Holland attempted an unconventional muscle-definition technique ahead of filming a shirtless scene. The actor revealed details about his experimental approach in an interview published in early August, explaining that he had experimented with a dehydration method commonly employed in the bodybuilding and competitive fitness communities. The technique involved restricting water intake on one day, then consuming significant amounts of water the following day, with the intention of temporarily reducing water retention beneath the skin to create the appearance of more defined musculature.
Holland disclosed that he implemented this strategy while preparing to film a Russian bathhouse scene alongside actress Florence Pugh, who reprises her role as a character in the film. The scene required Holland to appear shirtless while his character undergoes a security check. Despite his commitment to the preparation method, the actor acknowledged that the results fell short of his expectations and created an unintended consequence that proved counterproductive to the filming process.
- Filming location: Glasgow, Scotland, in August 2025
- Scene context: Russian bathhouse sequence with actress Florence Pugh
- Method employed: Strategic water restriction and consumption cycling to reduce subcutaneous water
- Primary outcome reported: Increased irritability without meaningful physical improvement
Why It Matters
Hollywood’s approach to physical transformation for film roles continues to generate discussion about the methods actors employ to meet production demands. Holland’s experience illuminates the gap between theoretical effectiveness and practical results when implementing extreme preparation techniques. The actor’s candid assessment that the dehydration approach failed to deliver meaningful visual benefits while creating negative physiological and psychological effects raises questions about the utility of such methods within the film industry. His willingness to discuss the unsuccessful experiment provides insight into the behind-the-scenes pressures actors face when preparing for specific scenes that require particular physical presentations.
The incident also reflects broader conversations about wellness and body image within entertainment. While certain techniques may offer marginal benefits in controlled competitive environments, their application in film production contexts presents different challenges, including the need to maintain energy levels, focus, and emotional stability during filming. Holland’s report that the method primarily resulted in mood deterioration without corresponding visual improvements suggests that actors and production teams may benefit from reconsidering such approaches in favor of alternative preparation strategies that do not compromise performance quality.
- Actor performance impact: Irritability affecting on-set demeanor and interactions
- Visual effectiveness: Limited muscle definition improvement relative to effort and discomfort
- Industry practice questions: Whether extreme techniques justify their physiological costs
- Professional relevance: Implications for how production teams approach physical preparation for cast members
Political and Public Context
The entertainment industry has long documented various physical transformation techniques employed by actors preparing for specific roles. Precedent exists for actors across multiple high-profile film franchises attempting aggressive body-composition methods to meet production requirements. These practices reflect both competitive pressures within the industry and audience expectations regarding on-screen physical presentation. Holland’s experience joins a broader narrative of actors publicly discussing the demands and consequences of intensive physical preparation for film roles.
Other actors have previously disclosed similar experiences with dehydration techniques used for shirtless scenes in major productions. The methodology represents a segment of Hollywood’s approach to temporary physical enhancement, though discussions regarding the health implications and effectiveness of such methods continue to evolve. Industry professionals, including trainers and medical advisors working in film production, increasingly emphasize sustainable approaches to physical preparation rather than extreme short-term tactics. Holland’s candid assessment that his experiment proved counterproductive aligns with emerging perspectives within production communities that prioritize actor wellbeing alongside meeting visual requirements.
- Precedent: Other major film actors have employed similar dehydration strategies for production
- Industry evolution: Growing emphasis on sustainable physical preparation over extreme techniques
- Professional standards: Increasing consultation with medical and fitness professionals regarding safe preparation methods
- Actor transparency: Growing candor from performers discussing unsuccessful physical preparation experiments
It’s an ill-advised technique, even for superheroes.

What Happens Next
Holland’s public disclosure regarding his unsuccessful dehydration experiment may influence how future production teams approach physical preparation requirements for actors. As more performers share their experiences with extreme preparation methods, production companies may implement adjusted guidelines that emphasize effective and sustainable approaches rather than potentially counterproductive techniques. The actor’s feedback that the method failed to deliver meaningful results while creating negative side effects could serve as a cautionary reference point for other industry professionals evaluating similar preparation strategies.
The Spider-Man: Brand New Day production continues with its scheduled timeline, with Holland and the broader cast moving forward with standard professional preparation methods. Film industry conversations regarding optimal approaches to temporary physical enhancement for specific scenes will likely continue, potentially informed by Holland’s public assessment of his failed dehydration experiment. Future production decisions regarding whether to require or recommend such techniques for actors may reflect the growing body of evidence that such methods often fail to justify their costs in terms of actor comfort, mood, and overall performance quality.
- Production team approach: Potential reassessment of physical preparation requirements for future scenes
- Industry guidance: Possible influence on professional standards regarding actor preparation methods
- Actor preparation alternatives: Continued exploration of more effective and sustainable physical enhancement strategies
- Spider-Man: Brand New Day: Ongoing filming schedule with completion timeline expectations
