Faire son cinéma, literally “to do one’s movies”, means to be dramatic, to exaggerate, to make a big fuss! There are different versions for that expression – faire son cinéma, faire du cinéma, faire tout un cinéma but they all mean the same!
Obviously, the expression, that dates back to the middle of the 20th century, comes from the movies and the actor’s ability to play a role!
