Sometimes A Cigar Is Just A Cigar
Gary Westfahl has just reviewed The Road for Locus Online:
Like the novel, the film is deliberately vague about precisely where in America the man and son are traveling south, but in one scene the father shows his son a fragment of a map to indicate their progress toward the coast, and we see that they are approaching a coastal city named Outland. Because I can locate no evidence that such a coastal city actually exists, this may be a reference to Berkeley Breathed’s sardonic comic strip about small-town America, Outland (1989-1995), to the 1981 film Outland (a version of High Noon in outer space featuring a lonely hero surrounded by villains), or to the World of Warcraft game’s “extradimensional realm” Outland, constructed out of the shattered remains of an orc planet.
I think we can safely assume that yes, this is a reference to World Of Warcraft.
