Harry Potter mania is about to hit. Harry Potter and the Order of the Phoenix is out in US theaters on Wednesday while the last book in the Harry Potter series, Harry Potter and the Deathly Hallows, is out next Saturday, July 21.

Advance reviews for the film are overwhelmingly positive, with a current 87% aggregate critics rating on Rotten Tomatoes. Several critics have written that it’s the best Harry Potter film yet, and that it’s darker and scarier than its four predecessors.

As for the book, I have to admit I’ve read all the other Harry Potter titles and although I won’t be waiting in line for it I’ll be sure to snatch up a copy within a few days of its release.

Diehard Harry Potter fans are planning a media blackout next weekend so that the end is not spoiled for them. JK Rowling has said that two characters will die at the end of the series, and a lot of speculation has surrounded her claims. She said she was crying while writing the end of the book and that she was devastated to end it. Fans want to know who dies, but not until they get a chance to read the whole book first.

Now, as the July 21 release of the seventh and final book in the series, Harry Potter and the Deathly Hallows, approaches, fans who have waited the better part of a decade to find out the ultimate fate of Harry, his friends and his nemeses are taking no chances.

But how far do they have to go? Must they close their eyes, cover their ears and scream, “LALALALA?”

Pretty much. In fact, if you want to get in touch with a rabid Harry Potter fan on the weekend of July 21-22, you might be out of luck.

Readers are planning media blackouts — no computers, no cell phones, no TV, no radio. And if that’s not enough, they’re threatening to get physical.

“I’ll beat the crap out of the person who spoils it for me,” Pritthish Chakraborty wrote in an e-mail. Chakraborty, 17, who runs a fan Web site, Harry Potter Beyond, in his native Bangladesh, was spoiled two years ago when a “friend” sent a picture message to his cell phone of the page describing Dumbledore’s death.

Many fans don’t want to give up the excitement and camaraderie of a midnight release party, but they know they’re putting themselves at risk.

“We advise people — I know this is terrible — to bring headphones to the book release and put them on as they leave the store so they’re not subject to the idiot across the street screaming the end to them,” said Melissa Anelli, a webmaster of the Leaky Cauldron, a prominent Harry Potter fan site.

In 2005 some fans were upset to have the end of the last book yelled out at them as they left bookstores early in the morning of the release.

I’m the kind of person that can’t resist looking up spoilers, but that wouldn’t keep me from reading the book as all the fun is getting there.

Here are pictures from the LA premiere of Harry Potter and the Order of the Phoenix including Daniel Radcliffe. Emma Watson with brother, Alex, Rupert Grint, Imelda Staunton, Melissa Joan Hart, and Masi Oka. Rupert Grint is wearing a cute shirt with a picture of Harry on it.
