Cameron still connecting the dots on Avatar sequels

Director James Cameron says that writing three Avatar sequels is such a complex job he's delaying the first new film for a year, and it will now be released in late 2017.

Cameron plans to film the highly anticipated sequels all at one time and then release the three films over consecutive years.

The first had been due in late 2016, but he said the writing process had proved to be "very involved" and that the initial target date was probably too ambitious.
