The Stories behind the Goblet of Fire DVD March 7 and March 20 release dates...

Despite being filmed mainly in England Harry Potter and the Goblet of Fire will be released on DVD in the US two weeks before fans can get it in the UK.

Warner Bros has confirmed the DVD will be out on 20 March in the UK, but US kids will have it from 7 March.

The DVD will have special features including behind-the-scenes footage and interviews with Daniel Radcliffe, Rupert Grint and Emma Watson.

Warner Bros said the difference in dates was a matter of "scheduling".

People who buy the DVD will be able to take part in the action as the makers have created three interactive challenges based on the exciting Triwizard Tournament and a fourth called To the Graveyard and Back.

Viewers will also be able to see how sections such as the underwater lake scene were made, as well as getting a sneak peek at how the Yule Ball and other scenes were filmed.
