During one break in the filming, he was a fatuous British director, “exploring the essence of what we call cinema!”
He was cleverer than most everyone else, but he envied the carefree affluence of the rich and fatuous.
I also won't repeat, or defend him against, all the fatuous charges leveled against him.
Latin fatuus 'foolish'
c.1600, from Latin fatuus "foolish, insipid, silly;" of uncertain origin (Buck suggests originally "stricken" in the head). Related: Fatuously; fatuousness.
