AceShowbiz - Aaron Taylor-Johnson, best known for his portrayal of Quicksilver in 2015's "Avengers: Age of Ultron" and the recent Kraven in Sony's Spider-Man universe "Kraven the Hunter", recently spilled some behind-the-scenes secrets that might surprise Marvel fans.

During an interview with Capital, the 34-year-old actor addressed a widely speculated but rarely confirmed practice in superhero filmmaking: the use of padded costumes to enhance an actor's physique on screen.

For his latest role as Kraven, Taylor-Johnson underwent an intense transformation, gaining 40 pounds of muscle through rigorous training and a substantial diet. Reflecting on this, he commented, "I trained and ate so much f***ing food."

However, he said that not all Marvel stars take the same challenging path. "I've worked on some Marvel films. You know those suits are padded," Taylor-Johnson disclosed. When asked to clarify if these suits included "built-in six-packs," he confirmed, "Arms, everything. … I've seen some crazy pads. That's me dishing some dirt."

But he stopped short of naming which actors might be using these enhanced costumes.

This revelation has stirred a mix of reactions among fans, especially those who idolize the herculean images of their favorite heroes. While it's common knowledge that actors undergo intense physical training for their roles, Taylor-Johnson's honesty provides a more nuanced perspective on the superhero image. Even with advanced fitness regimes, elements of costume design play a key role in achieving the polished final look seen in theaters.

Understanding that movie magic often involves more than just the physical efforts of actors can lead to greater appreciation of the collaborative efforts behind the scenes. Whether it's through rigorous physical preparation or a little help from well-designed padding, the creation of a superhero is a complex and multifaceted process.

As Marvel continues to evolve and expand its cinematic universe, fans can look forward to seeing their favorite characters brought to life - whether through sheer muscle or the artistry of costume design.
