Well, the first day of the D23 Expo is finally upon us. Not too much ground-breaking news has come out yet, but we do have some stuff for you. First up, the OC Register’s Around Disney blog reports from Bob Iger’s opening speech at the D23 Expo this morning:

Audience members squealed as soon as Zac Efron’s face popped on the screen. They clapped when “Princess and the Frog” movie footage started. And a few random enthusiasts screamed when “Radio Disney” was mentioned during a speech.

The fans were the reason for this convention: the D23 Expo, the first-time, four-day event put on by the Walt Disney Co. that began today.

“The excitement that keeps us going year after year comes from you — the fans,” said Bob Iger, the company’s president.

Iger gave the opening address today on the first day of the four-day expo in front of thousands of audience members at the Anaheim Convention Center. The opening presentation included a video showing the diversity of the company — from theme-park footage to scenes of “High School Musical,” starring Efron.

The opening 30 minutes of the upcoming movie, “Princess and the Frog,” –one third of the film — was shown for the first time to the public three months before it goes to the theaters.

After the preview, actress Anika Noni Rose, the voice of main character Princess Tiana, came out in a sparkly, off-white dress to perform a song from the movie. Iger said Rose had been suffering from bronchitis.

Anaheim Mayor Curt Pringle followed on stage, joking that he was the frog after the princess.

The presentation concluded when an audience member — Dan Learn of Murrieta — was awarded a night’s stay in the Dream Suite at Disneyland. During a followup press conference, Iger said: “I haven’t stayed there.”

Here are some photos and videos Disney released from inside the Expo today:
