CNN features a report on some of the charity screenings, which took place May 12th at various locations. Here's a short blurb on each of the cities they cover. Click on the link above for the full report:

San Francisco:

A red carpet lined the side of the Sony Metreon theater in San Francisco and volunteers dressed like stormtroopers, X-wing pilots and bounty hunter Boba Fett. Fans gathered for a glimpse of director George Lucas.

New York:

Jake Lloyd, 16, who played the young Anakin Skywalker, says he's transitioned into a normal life. "It's like the end is here," he said of the final film. "It's part of cinematic history."

Los Angeles:

Hamill, who played Luke Skywalker in the original episodes, ran across the street to shake hands and sign autographs. The premiere also drew "Frasier" star Kelsey Grammer, who said he interviewed for the role of Han Solo in the first "Star Wars" film but didn't get it.

Atlanta:

At Atlanta's Phipps Plaza shopping mall, red carpet patrons entered the theater as white-armored stormtroopers greeted everyone who passed by. Amy Allen, who plays the Blue Jedi in Episode III, said she's been "waiting for this moment for a very long time."

Denver:

Moviegoers at a theater in suburban Denver were greeted by costumed members of the Rocky Mountain Fan Force, a group of Star Wars fans who appear in costume at charity events.

Washington DC

Carrie Fisher -- Princess Leia in the original trilogy -- attended the Washington, D.C., premiere.

Miami:

And in Miami, premiere organizers planned to re-create the cantina scene from the original "Star Wars."
