In truth, I can only think of two movies where this really seems to apply: 1998's The Truman Show , whose excoriation of what was then the new form called "reality television" seemed like fantasy at the time and now feels like something that could happen tomorrow if they figured out a way around the legality, and 1976's Network , in which the gorgeously erudite writer Paddy Chayefsky spun a tale of how the news media at its worst is a whorish sinkhole in which the most wretched and violence impulses of humanity are turned into exploitative nonsense to get you good and bloodlusty before the dish soap and car insurance commercials.
In its themes it recalls such films as "Network" and "Natural Born Killers."
Once its premise is set forth, ready-made for easy pontification, ''The Truman Show'' doesn't go on to echo the prophetic intuitiveness of ''Network'' or even send up the lurid voyeurism of popular culture today.
This is not "Network" but a highly enjoyable romp featuring the very talented Jim Carrey, who fulfills Weir's promise as the best actor around for Truman's role.
Perhaps no other film since 1976's "Network" has had the potential to inspire such a debate about the effects of the media on our very societal structure.
While echoing "Network," "Capricorn One" and "1984," as well as the cult television series "The Prisoner," "The Truman Show" defines its own niche.
