"Today's the day!," director Michael Moore says in a letter urging fellow Americans to rent or buy the DVD of his award-winning "Fahrenheit 9/11" and "use as your own personal weapon of George Bush's mass defeat."
The box-office smash documentary, which could prove a high-caliber weapon against the incumbent president, hit the market on Tuesday - less than a month ahead of the November 2 US presidential vote, with Bush and rival John Kerry in what polls show is a very tight race.
The DVD version - which raked in almost 120 million dolle also has launched two books:
"The Official Fahrenheit 9/11 Reader" to accompany the documentary and "Will They Ever Trust Us Again? Letters From the War Zone" which were written to Moore.
According to Moore, "all surveys have shown that, the more people who see it - especially those still sitting on the fence - the more likely we will have regime change come November 2nd."
The director has opted not to present the film as a candidate for a best documentary Academy Award and instead have it televised the day before the vote. It also can be considered for best picture at the next Oscars ceremony on February 27.
With the race neck-and-neck Moore made sure the DVD, its second coming, fell not long before the presidential vote.
This latest version of the documentary also includes new footage from the Abu Ghraib prison scandal where US troops were photographed abusing Iraqi prisoners, as well as previously unreleased testimony by Bush's national security adviser Condoleezza Rice to the September 11 investigating commission, and further words from Bush.
According to Moore, it is "footage so frightening you will understand why the networks never showed it to you."
"May I suggest that you take this DVD and run with it? Use it as a way to energise people of like-mind or convince recovering Republicans that this may be the most important election of our lifetime," Moore offers, suggesting neighbourhood and school showings and loaning the DVD out.
Republicans and conservative groups did not stand idly by: also out Tuesday was the DVD "Fahrenhype 9/11" with a companion book that calls into question Moore's data and questions his documentary-making motives.
A documentary by US filmmaker Mike Wilson, called "Michael Moore Hates America," was shown in Los Angeles over the weekend and aims to counter the impact of Moore's highly political home run.
In Washington this week another documentary "Celsius 41.11" was released; it refers to the temperature at which the human brains begins to be destroyed by heat. Funded by a conservative group Citizens United, it too questions Moore's stands.
