One thing that defines scripts and films in general is the tittle. Some titles are so iconic that once you mention them you pretty much have a full on breakdown of the story.
One funny thing about titles is that they don’t always start out the way they end up. A classic example of title changes was Butch Cassidy and the Sundance Kid.
Originally the title was Sundance Kid and Butch Cassidy. The title was switched when Paul Newman took over the lead role. The film wouldn’t have been any less successful, or less classic had the title not changed, just really odd to pronounce.
