In The Great Moment, writer/director Preston Sturges turns to a more serious subject matter focusing on one of the great medical discoveries in modern history. Inspired by the true life story of Dr. William Morton, a dedicated dentist (Joel McCrea) discovers ether, otherwise known as anesthesia, in 1846. The doctor's great contribution to humanity, the tribulations he later faced sharing his knowledge, and his reluctance to capitalize on his discovery, are meticulously laced with typical Preston Sturges humor and drama.
