Future Steven Spielbergs were being given a chance to show off their movie-making skills and get a sneak preview of scenes from the new Harry Potter film this weekend.

Budding film-makers were at the National Museum of Photography, Film & Television for the annual Co-operative Young Film-Makers Festival.

With more than 360 productions from creative individuals, schools, youth groups and colleges, this year's festival was the biggest ever, and attracted entries from Aberdeen to Devon.

A Hollywood blockbuster special effects seminar revealed behind-the-scenes trade secrets and the magic that went into creating Harry Potter's school.

The organisers held a number of other workshops, seminars and panel discussions covering prosthetics and make-up, fight choreography, animation and claymation, acting, and how to make short films. Amy Heale, 13, is pictured having her face made up by special effects student Nadine al-Samarrie.

Festival organiser Phaedra Patrick said: "The festival has always been popular in Yorkshire and we again hope to support local young film-makers and their counterparts across the UK.

"The event provides a great opportunity for budding movie moguls to showcase their talent on the big screen and audiences could be lucky enough to see the early work of the next Steven Spielberg.

"Bradford is an ideal location because it is centrally located so people can come from all over the UK and the museum is excellent, it has everything we need in terms of space and the screen and rooms to hold the workshops."

Fight choreographer, Kevin Rowntree, who worked alongside actors like Russell Crowe, right, on the Hollywood blockbuster Gladiator has been part of the festival for four years.

Mr Rowntree held workshops about stage-fighting in the films The Matrix and Fight Club.

He said: "This type of festival is great because it's a wonderful opportunity for young film-makers to engage in workshops and learn more about specific techniques of the industry."

"It's good to be outside of London and to have a regional film festival that offers a national platform for young people."

Pupils at Newhall Park Primary School in Bierley were at the festival for a special screening of their short film. It was the third year the school has been chosen to take part in the event.

Martin Naylor, the school's caretaker who runs the film club, said: "Now we know our film is very good and there must be lots of reasons why the judges decided to put our film into the festival.

"It could be because the films content and message is so appealing, or it could be because the film shows a true story of how a small group of children brought about a change to the time-table of their own school.

He added: "Our film uses the BBC news signature tune throughout the film, and of course is a very good example of the co-operation between two very different organisations, the giant BBC and a primary school in the north if England."

Festival advisor, Cadi Callow started out as an entrant to the festival and 15 years later runs her own animation company, 3 Bears Animation.

She said: "Because all the events are free, and the advisors are volunteers the festival is accessible to more people and we can put on more events."
