Mjolnir and Stormbreaker: Weights and Props in the Marvel Cinematic Universe

In the Marvel Cinematic Universe (MCU), the exact weights of the famous Mjolnir and Stormbreaker are not officially stated. However, based on various sources and prop details, we can gain a good understanding of these formidable weapons' weights and how they are handled in the films.

Prop Specifications: Mjolnir

The prop used in the MCU for Mjolnir is estimated to weigh around 20 pounds, approximately 9 kg. This significant weight is carefully managed for the actors, ensuring that the footage maintains a sense of the weapon's power and presence without making it overly burdensome to wield. Mjolnir's manageable weight enhances the believability and authenticity of the scenes featuring the weapon.

Prop Specifications: Stormbreaker

Compared to Mjolnir, the prop for Stormbreaker is generally considered to be heavier, with estimates ranging from 30 to 40 pounds, or approximately 14 to 18 kg. This increased weight is reflective of its larger size and more intricate design, contributing to its imposing presence on screen. The weight difference adds to the narrative of these weapons, making Stormbreaker a more substantial and formidable tool.

Understanding Movie Props

There are several types of props used in movies, each serving different purposes depending on the scene and the action required. Here's a breakdown of the different kinds of props:

Hero Props

A hero prop is typically used for close-ups and scenes where the prop is not actively engaged in action or movement. These are the detailed and often highly accurate versions of the weapon or tool. The weight and material used in a hero prop might be carefully chosen to reflect the weapon's authenticity, though it is not necessarily the prop used in every scene.

Action Props

For scenes involving running, fighting, or other action sequences, a different kind of prop is used. These are often made of materials like rubber or foam to ensure that they do not cause injury to the actors, other actors, or stunt personnel. These props are designed to withstand the rigors of action scenes without compromising the safety of the crew.

Stunt Props

Some stunts require specific props that are used only for the execution of particular actions. For example, the prop used for Mjolnir in actions like throwing or flipping might differ significantly from the hero prop. These stunts require robust and wear-resistant materials to handle the physical demands involved.

A prime example is the handling of firearms in movies. During scenes where characters are not firing a weapon, they typically wield a rubber or foam prop. When the character needs to fire the weapon, a real, loaded gun is provided by a prop handler who keeps it safe. The real gun is given to the actor just before filming and is immediately retrieved once the shot is complete to maintain safety.

Comic vs. MCU: The Weights

In the comics, Mjolnir is often stated to weigh 42 pounds. However, in the MCU, the hero prop, being used for close-ups and detailed shots, would likely weigh a couple of pounds more or less, depending on the specific needs of the production and the on-screen authenticity desired.

Understanding these weight differences and the types of props used in different scenes provides insight into the meticulous attention to detail that goes into bringing these legendary weapons to life on screen. This attention to authenticity and practicality ensures that the MCU's take on Thor and his weapons remains both believable and engaging for the audience.
