A lot of journalists like to suck up to celebrities and then as soon as they're a safe distance away at their computers they take shots. But that's the way society has become especially in pop culture.
One of the main reasons I am so drawn to Hitchcock is that he planned his shots way in advance on story-boards which he designed like classic paintings (he was an art connoisseur). It's why he found shooting on set boring - because he had already composed the film in his head.
