Ricky checked out a touring trailer which was packed with props and costumes from the Harry Potter films! It's in London's Leicester Square until Sunday.
Actors dressed in Hogwarts-style costumes ushered him into the trailer. The show is available on a first come, first served basis.
The show has costumes for some of the biggest characters - including this, worn by the boy wizard himself!
Professor Slughorn wears these togs in the new movie, Harry Potter and the Half-Blood Prince.
The film, out on 15 July, feature statues like this one of a gryffin.
Here's a genuine Quidditch broomstick and a very familiar hat!
This costume is worn by Dumbledore in the films - but will he be filling it in the next movie?
