Many years, and many film sets later, I heard from a friend who was working on a movie that mixed cute furry farm animals with cutting-edge technology. I knew instantly I had to get smuggled in on this one.

That film is now one of the most cherished children's classics of the 1990s - Babe. It has been 25 years since the talking pig first appeared on international screens and revisiting the film today shows it has not lost any of its charm or wonder.

Directed by Chris Noonan and starring James Cromwell and Magda Szubanski as farmers Mr and Mrs Hoggart, Babe made more than US$250 million (A$351 million) at the international box office. It spawned a (much less succesful) sequel, Babe: Pig in the City in 1998.

The story of a young piglet raised by a border collie to become a sheep herding star was a crowd favourite not just because of the cute animals, but because of the dazzling technology, which makes these animals look like they really are speaking.

With its story of achieving in the face of adversity, coupled with simple lessons - cooperation is better than intimidation, you can aspire to more than what others expect of you - Babe still appeals to both adults and children alike.

When I got to Bowral, NSW, no one could resist telling me Hollywood had come to the region. Ask anyone where Babe was filming and they pointed along the road to Robertson, a 25-minute drive east, through gentle hills and valleys surrounding a small village.

It was not long before the conglomeration of film trucks, tents and trailers came into view. But the thing that really caught my eye was the pens full of animals - dozens of sheep, chickens, cows, dogs and pigs.

Because filming took months, the production needed to constantly bring in new baby animals - the ones they filmed one week would soon grow too large and need replacing.

I was used to the hustle and bustle of a hot set, but this was like a circus.

Why was Babe such a massive hit? The combination of computer graphics and animatronics used is common now, but then was known only to a few specialists: the movie even beat Apollo 13 for the Oscar for best visual effects.

Still, while Babe was a film big on technology it didn't let the multi-million-dollar special effects get in the way of the story and characters. The heart of the story was always the animals. Children feel a strong bond to the animals in the film because they are portrayed as child-like themselves. In Babe, the central character is a piglet and speaks with a child's voice. He has a sense of innocence and wonder.

As a kids' movie, Babe also took big risks. The pigs, sheep and cattle on Hoggett's farm were explicitly meat animals and the scene where Babe is told humans eat pigs is particularly disturbing for younger viewers. But these risks are handled sensitively, and pay off.

It has even been said these scenes sparked positive arguments for animal rights: Cromwell became vegan after filming, and PETA calls it "a classic animal rights movie".

I think the reason the film was embraced internationally was because it isn't what we would classify as an "Australian" film. Hoggett's farm looks more Dorset or Devon in the south of England and there are no kangaroos or koalas in sight. Even the accents are a global mish-mash.

Audiences of all nationalities could enjoy it because it was truly international. Ultimately, though, Babe stays in our hearts and minds because it was a good story, well told. Do we really need anything else? That'll do, pig, that'll do.
