I lived and worked in Hollywood for several years. Practically everyone knows someone who works in the industry, and copies of movies are always floating around before they even hit the theaters. Thousands of studio employees all bring them home, they make copies for all their friends and relatives and neighbors... everyone has them. And they’re good copies too... not some crap recorded in a theater by some amateur.
Just as I thought. There are many places along the production line that a movie can be ‘stolen’ and I’m sure that the movie industry makes more copies than they intended..................
