A while ago it was revealed that Disney was working on its first straight-to-DVD movie based on a Pixar flick, a spin-off from Cars called Planes. If you’re wondering why they’d bother with this, seeing as Cars is normally seen as a lesser PIxar movie, the fact is as a franchise it’s currently the biggest thing Disney has, having sold billions in merchandise. Indeed, with the release of Cars 2 this summer, the House Of Mouse expects to make more in merchandising from it than they did from Toy Story 3 last year, irrespective of whether it does the same business in cinemas. So it does make sense to do a spin-off, even if most of the world likes to think of Pixar as being above such things as thinking about profit (and technically this isn’t a Pixar production, instead being produced by Disneytoon Studios. Anyway the first teaser trailer is here, and while it doesn’t show us much, it does look like it might be fun. It should be out nexy Spring.
