Filmmaking- What are props and their use in films

• Prop is nothing but an object used with respect to story in films like gun,sunglasses,chairs etc.
• You can say non living actors in a movie are props .
• putting objects randomly in a scene is bad directing
• A director should analyse why a particular prop is used,in what camera angle it should be in ,is prop is directly related to the character or environment
• For an example In some movie characters will have a favorite car which will be in movie most of the time and it is independent on environment
• If a bar scene is there then bottles are used as props and it is relative to the environment
• So props are highly useful devices which will carry forward the story
