Weapons as Props
When using a weapon for your scene, safety must always come first – for both you and your co-actors.
Accidents can and do happen with both real and fake weapons during rehearsals and performances. It is important to pay attention during the weapons training you will receive. These lessons are just as important as your acting training. Knowing what you are doing will help make your scene look more authentic and keep you and fellow actors out of harm's way.
It is a good idea to inspect the area where the weapon will be used before the scene. An actor running with a blade could trip and fall onto the blade or another actor. To prevent this, check the floor for hazards. Additionally, actors using weapons should wear protective gear under their costumes whenever possible.
Any scenes involving weapons or explosive effects are always extensively rehearsed and choreographed to ensure maximum safety while making the scene look very dangerous.
