Doctor Who sidekicks to feature in new BBC mini-series Pond Life
Karen Gillan and Arthur Darvill's characters will be the focus of five short online episodes, ahead of new Time Lord series
Doctor Who fans will get a glimpse of Pond Life in a new mini-series about the Time Lord's sidekicks.
The five short episodes will be shown online ahead of the start of the new BBC series on 1 September and will focus on the characters played by Karen Gillan and Arthur Darvill.
Writer Chris Chibnall said: "Pond Life provides us with a lovely opportunity to catch up with Amy and Rory since we saw them at the end of the last series.
"It opens with them at home and gives us an insight into just what happens when the Doctor drops in and out of their lives.
"Travelling with the Doctor is one of the greatest things you can do, but it's fun to spend a few moments looking at the chaos he can also bring."
Pond Life will be shown online over five days from Monday 27 August on the official Doctor Who website and the BBC1 YouTube channel – it will then repeated in an omnibus on the red button on Saturday 1 September.
The actual series returns with the first of five full episodes on the Saturday at 7.20pm on BBC1.
