20-odd years ago, nearly all animated movies came with a short cartoon that preceded them, but now Pixar is virtually the only company left doing that. However it does mean we’ve had some great treats over the year, including the likes of For The Birds and Presto. The short that will come with Toy Story 3 is Day & Night, featuring two hand-drawn characters, one of them day and one night, who instead of just being coloured in, have a CG world you can see going on inside/behind them. It’s a pretty strange idea and difficult to explain, but makes sense when you see it, which is probably why this featurette was released, giving us a look at the concept and how they came up with it. Click below to watch. Toy Story 3 and of course Day & night, reaches UK cinemas on July 17th (we think, as the date keeps creeping forwards, but that was the last we heard).
