Walking the red carpet with fellow co-stars Bonnie Wright and Tom Felton, Rupert Grint (a.k.a Ron Weasley) said: 'This is the most glamorous I have ever seen Watford. It’s exciting for everyone to see.

'There are so many memories from there and to share them with everyone is great. The model of the castle is out of this world.'

The 23-year-old also added that he couldn't resist taking home some mementos, pocketing Harry's door number from his house on Privet Drive.

Burberry model Eddie Redmayne also checked out the new attraction.
