You might notice a lot of similarly dressed people in the Universal Orlando area this weekend. They're also putting a slight dent in the Earth because thousands of these robe-wearing, scarf-sporting, wand-touting fanatics want and need everything Potter.

The second annual "A Celebration of Harry Potter" has just kicked off at Universal Orlando. Last year, fans were anticipating the forthcoming grand opening of the second Potter-themed section, Diagon Alley. But this year, they get to experience the new land in addition to the original Hogsmeade.

Costume-clad Eleni Panagiotidis, 12, flew in from Connecticut with her family to attend the weekend-long event.

"It was just a book," she said, of the franchise. "But honestly, it's been my best friend throughout my whole life."

Just check out the mural just inside the entrance of the Harry Potter Expo at Universal Studios. Fans can respond to "What Does Harry Potter Mean to You," and the messages are quite emotional.

For instance, someone scribbled: I was hospitalized for months from many surgeries. ... Thank you for helping me recover." Also, we saw this one: "Harry Potter lets me be myself without being judged. I always watch them when I am in a bad place or feeling ill. Thank you, J.K. Rowling."

"It's just like a home away from home," Panagiotidis said. "It's — it's just amazing."

"For me, it's definitely something I grew up with," said a robe-wearing Modjeska Hutchings, visiting from Kingman, Arizona. "So, it's been important to me over the years."

Also inside the Expo are real-deal props and costumes from the film sets.

"All the props come from Warner Bros. Studios," said Eddie Newquist, of Harry Potter: The Exhibition. "They've allowed these out of their archives for the fans to see here in Orlando."

Here's an incentive to stay active this weekend and attend the demos: We learned some of the film actors will be making surprise appearances. 

Here's some more information we got from Universal. The event will include experiences such as:

  • Q&A sessions with film talent and other special guests, including Michael Gambon (Albus Dumbledore), James Phelps (Fred Weasley), Oliver Phelps (George Weasley) and Evanna Lynch (Luna Lovegood)
