Many critics and viewers of this movie noted that the plot bore many essential similarities to Theodore Dreiser's 1925 novel "An American Tragedy," as well as the movie version of that novel, A Place in the Sun (1951), starring Montgomery Clift, Shelley Winters, and Elizabeth Taylor. Despite the unmistakable similarity between the plots of "An American Tragedy" and Match Point (2005), however, there was no acknowledgment of Dreiser in the credits, and Match Point (2005)'s only Oscar nomination was for Best Original Screenplay (not Adapted).
