Filming in public always attracts attention from onlookers. People are curious to what is happening on set. You have to be mindful how people may perceive what is happening on your set, especially when using prop weapons, conducting stunts, or if people are acting angry or distressed. It is a good idea to have members of your crew posted so they can let the public know what is happening. Always make sure that you have permission from owners if you are filming in front of their place of business, and be sure not to obstruct the way of any potential customers. Permits has to be granted to film on certain beaches and National Park lands, so make sure you follow the proper channels to gain permission to film in those spaces.
