All the actors said they were really impressed with the size and detail of the whole attraction. It's much bigger than the movie sets and some of them were actually moved just walking through the attraction.

"I had a rather emotional moment actually, because it was kind of like bits of your life suddenly, you know, made real," said Coltrane.

The actors also got to sample Butter Beer, a drink from the Harry Potter books, which will be served exclusively at Universal Orlando.

The attraction officially opens on June 18 at Universal's Islands of Adventure.

The Potter area will be Universal's third big-ticket addition in three years. SEC filings from the company estimate the combined cost of The Simpsons Ride, Hollywood Rip Ride Rockit and Wizarding World at between $275 million and $310 million.

The Potter park is sure to prove popular not just with American fans but also with visitors from the United Kingdom, Potter's home and already the largest source of international tourism to Orlando, with about 1 million arrivals a year.
