Cinema is a kind of pan-art. It can use, incorporate, engulf virtually any other art: the novel, poetry, theater, painting, sculpture, dance, music, architecture.

Susan SontagI feel inauthentic at a party. ... Going to a party is a 'low' activity - the authentic self is compromised, fragmented - one plays 'roles.' One isn't fully present, beyond role-playing. One doesn't (can't) tell the full truth, which means one is lying, even if one doesn't literally tell lies.
