How do I stop being angry at someone?

I am working with someone in a film crew. I am director they are cinematographer. I am having a very hard time keeping my cool around them because of 1) their condensing expressions and tone of voice 2) their sense of entitlement towards the film’s script (while I do take their notes into consideration, they are offended when I don’t use all of their edits) 3) They keep giving me flack for every aspect of the film, though being director I am not directly responsible for what other crew members get done. Basically I’ve brought it up that their tone and attitude towards me is rude and they say that it’s all for the betterment of the film. What do I do?
