What if you could make your own film presenting your take on the Harry Potter character (someone in Georgia might be interested) or your opinion of what should have happened in X-Men: The Last Stand (comic book geeks everywhere wish they could)? Unfortunately, most fictional films involve intellectual properties and copyrights and other things that (legally) cannot be messed with by just anyone.

The same isn't true for documentaries, which tend to present facts or deal with truth, concepts that people don't regularly own or control. These facts and truths are often debatable, though, and can be argued or debunked via other documentary films. Michael Moore's Fahrenheit 9/11 was answered with Alan Peterson's Fahrenhype 9/11. Morgan Spurlock's Super Size Me led to both Bowling for Morgan and Me and Mickey D. Robert Greenwald's Wal-Mart: The High Cost of Low Price was responded to with Ron Galloway's Why Wal-Mart Works: And Why that Drives Some People C-r-a-z-y.

The latest rebuttal doc is aimed at Al Gore's claims in An Inconvenient Truth. Steven Hayward has begun work on An Inconvenient Truth ... Or Convenient Fiction?, a documentary that will be formatted in the same way as Davis Guggenheim's award-winning doc on global warming. Hayward, like Gore, will present his own thoughts on the issue through a similar lecture and slide show. But he isn't going to disagree with global warming altogether, just specific points that Gore supposedly got wrong.

In his presentation, which is apparently shorter than Gore's, Hayward addresses the parts his adversary got right. "Much of what Vice President Gore says about climate change is correct," he says. "The planet is warming; human beings are playing a substantial role in that warming."

The argument then is with the issue of catastrophic emergency and alarm. Some things Hayward says aren't backed up by science include the consensus of human affect on global warming, the consensus on ice cap and glacier melting, and the predictions that the sea level will rise a cataclysmic rate and depth.

Hayward admits that his film won't be as popular as Guggenheim/Gore's, but he's hoping to at least provide for some alternative in the debate.

As for rebuttals to fictional films, let's see someone out there make a pro-diamond response to Blood Diamond or a Kazakhstani answer to Borat. Is Clint Eastwood the only filmmaker who knows how to represent both sides himself?
