Pyle's analogy states that "it is like seeing the trailer of a movie and saying you've seen the whole picture."
Ernie Pyle was a journalist who became a war correspondent during World War II, embedded with the soldiers and seeing what they saw at the battlefront. He told the story of the war from the vantage point of the fighting men -- what he called the "worm's eye" view of the war rather than the "Big Picture." Ernie Pyle won a Pulitzer Prize in 1944 for his stories of ordinary soldiers in the war. In 1945, he was hit by enemy fire and killed while with the soldiers on Iejema, a small island near Okinawa, Japan. In 1983 (posthumously), Pyle was awarded a Purple Heart for his valor as a civilian correspondent of the war.
