In contrast to Hitchcock's view of a MacGuffin as an object around which the plot revolves but about which the audience does not care, George Lucas believes that "the audience should care about it almost as much as the dueling heroes and villains on-screen."[18] Lucas describes R2-D2 as the MacGuffin of the original Star Wars film,[19] and said that the titular MacGuffin in Raiders of the Lost Ark was an excellent example as opposed to the more obscure MacGuffins of the next two Indiana Jones films.[18]
