There are many aspects that can be compared between the movie and the novella. These include setting, characters, and more. The discrepancies between the settings are very clear. The novella was set in the latter part of the nineteenth century, in a wild African Jungle frontier tracking the experiences of a group of men abroad the Congo River. The filmmakers took this setting and adapted it into a hostile Vietnam War setting. Vietnam was similar to the geographical setting of Heart of Darkness. Climatically, Vietnam was similar to the central African Congo region, with hot, humid weather conditions. Vietnam was also able to feature the intense jungle seen in Heart of Darkness. The river and its use as a method of transportation was an element of the book that could be used in the Vietnam setting. Also, the presence of native peoples was used in the film. These basic features of setting were left largely unaltered for use in the film. Some features however, underwent changes in order to suit the time period in which Apocalypse Now was filmed.

However, Willard and Marlow both have fascination that soon turned into an obsession with Kurtz. Also similar is the fact that Willard held the rank of captain, which is also Marlow's occupation. As to the character of Kurtz, the
