Viewed at the Festival de Cannes 2009

The opening film of this year's festival, and the first animated film ever to have this honour, Up is truly a film for all ages. The story of the adventures of an old man and a young boy, a flying house tethered to countless balloons, a long-lost (and mad) explorer, a giant bird called Kevin and assorted 'talking' dogs gets funnier and more exciting as it goes along.

This isn't slapstick humour, although there are some lovely visual gags, but deeper, more thoughtful. At times Up is even touching and poignant.

Visually, this is a treat and while I was sceptical about the use of 3D to begin with, it is built into the story so seamlessly that it really is worth the effort to seek it out. At the same time, I can't help feeling the 2D version could be even better because the 3D glasses had the effect of dimming the picture. The use of colour in the film is especially noteworthy, with various palettes used according to mood, character and phase of the story. Character voicing and music are also spot on.

I have no connection with Pixar, Disney or the film whatsoever, even if this review reads like a puff piece. The fact is, Up is an incredible piece of cinema, was a big hit with a very demanding press audience, and is worthy of your time and money.

Anyone who says animated films cannot amuse and entertain, while at the same time delivering any kind of emotion, does not know what they are talking about.

Up is so good I can now forgive Pixar for Cars!
