Having proven itself as a favourite film of children around the world, Willy Wonka & the Chocolate Factory is every bit as entertaining now as it was when originally released in 1971. There's a timeless appeal to Roald Dahl's classic children's novel, which was playfully preserved in this charming musical, from the colourful carnival-like splendour of its production design to the infectious melody of the "Oompah-Loompah" songs that punctuate the story. Who can forget those diminutive Oompah-loompah workers who recite rhyming parental warnings ("Oompah-loompah, doopity do...") whenever some mischievous child has disobeyed Willy Wonka's orders to remain orderly?

Oh, but we're getting ahead of ourselves ... it's really the story of the impoverished Charlie Bucket, who, along with four other kids and their parental guests, wins a coveted golden ticket to enter the fantastic realm of Wonka's mysterious confectionery. After the other kids have proven themselves to be irresponsible brats, it's Charlie who impresses Wonka and wins a reward beyond his wildest dreams. But before that, the tour of Wonka's factory provides a dazzling parade of delights, and with Gene Wilder giving a brilliant performance as the eccentric candyman, Wonka gains an edge of menace and madness that nicely counterbalances the movie's sentimental sweetness. It's that willingness to risk a darker tone--to show that even a wonderland like Wonka's can be a weird and dangerous place if you're a bad kid--that makes this an enduring family classic. --Jeff Shannon

Starring Gene Wilder in the title role, Willy Wonka and the Chocolate Factory may not be the most faithful Roald Dahl adaptation to hit the big screen, but there’s a strong argument that it’s the best. Even Tim Burton and Johnny Depp, with their 2005 release Charlie and the Chocolate Factory, couldn’t come close to this 1971 musical version.

Even nearly four decades later, it’s a surprisingly dark yet ultimately utterly joyful film, as Charlie Bucket finds his golden ticket and gets to join four gruesome children on a tour of the factory of the film’s title. What’s more, Willy Wonka and the Chocolate Factory is packed with toe-tapping, memorable musical numbers, a terrific cast of young performers, and a memorable lead performance from Wilder. His Willy Wonka is a complex creation, veering unpredictably between likeable and quite sinister. And it’s a performance that sticks in the mind long, long after the credits have rolled.

The Blu-ray release sadly doesn’t present the copious extra material in high definition, but the main feature has benefited from a solid improvement. It’s a bright, colourful and imaginative film for long periods, and the transfer work is up to the job. There are moments where the material shows its age a little, but this is a good upgrade from the DVD edition, and the picture and audio both show genuine improvements. It’s also the finest way to own what’s undoubtedly the best version of the book to make it to the big screen to date. As fine an actor as Johnny Depp is, his Willy Wonka simply doesn’t hold a candle to Mr Wilder’s…. --Jon Foster
