It's the sequel no one asked for! But money. Disney have released the first teaser trailer for the second film in an apparent Planes trilogy, Planes: Fire & Rescue. It's only about a minute long, but it feels much longer... That said, the animation's really nice.
The first Planes film was critically panned (it garnered a caustic 27% on Rotten Tomatoes), but made $206 million from a modest budget of $50 million. Disney will presumably be hoping for a repeat performance with what will be DisneyToon's 62nd (yes, really) film next year.
Planes 2 is directed by Bobs Ganaway (Secret of the Wings), with Julie Bowen (Modern Family) joining the cast alongside a returning Dane Cook. The film flies into cinemas on 18th July, 2014 in the US, and 8th August in the UK.
