'Michael Jackson's This Is It' Preview Tickets Sell Out Within Two Hours

All 3,000 tickets for Los Angeles screening sold out Sunday morning.

The limited two-week theater run of "[artist id="1102"]Michael Jackson's[/artist] This Is It" film guaranteed that tickets would be in high demand, and sure enough, all 3,000 tickets for Los Angeles advance screenings of the music documentary sold out within two hours early Sunday, according to The Associated Press.

The screening will take place the night prior to the October 28 nationwide release at the new Regal Cinemas Stadium 14 in Los Angeles.

The film follows Jackson as he rehearsed and prepared for a 50-date run of London concerts, which were scheduled to begin just weeks after his death on June 25. The film, which was directed by Kenny Ortega, will feature behind-the-scenes footage as well as Jackson and his band and dancers rehearsing for the tour.

Last week, it was confirmed that a two-disk album featuring a new song, "This Is It," will be released on October 27 to coincide with the movie's theatrical release. The new single will be released on October 12.

While the movie will open to the general public on October 28 for a two-week run, it will first hit theaters on October 27 in cities around the world, including Los Angeles, New York, Rio de Janeiro, London, Berlin and Seoul. Those cities will coordinate their screenings to begin three hours after the premiere at the Nokia Theatre in Los Angeles. Satellite transmissions of Hollywood stars' red-carpet arrivals will be broadcast to the other cities.

"Michael Jackson has an army of fans everywhere around the world," said Jeff Blake, chairman of worldwide marketing and distribution for Sony Pictures, said in a statement. "We are giving the audiences an incredible opportunity to join together in celebration of Michael Jackson's incredible career."

The news came on the same day a new clip from the movie was released, showing Jackson rehearsing the song "Human Nature"

for his planned series of 50 gigs at the O2 arena in London.
