Hide has been billed as a "Jekyll & Hyde tale by way of a conspiracy thriller". It stars David as a disgraced journalist who stumbles across a story that could resurrect his career. But he soon realises he has seen something he shouldn't have and is now being targeted by unknown enemies trying to silence him.

David and Georgia have been married since December 2011

"On the run as people around him go missing or die, a serious accident has an extraordinary side effect, and he realises there are monsters in the world – and he may be one of them."

Talent certainly runs in the Tennant family. Earlier this month, Georgia celebrated with fans as she revealed the couple's ten-year-old daughter Olive is set to make her film debut.

The couple share five children together

The little girl has taken on a role in Kenneth Branagh's Belfast, also starring Dame Judi Dench, Jamie Dornan, Ciarán Hinds, Caitriona Balfe and newcomer Jude Hill. It tells the poignant story of one boy's childhood amid the mayhem of the late 1960s.

Olive is the couple's eldest daughter and also the granddaughter of Peter Davison. She made a cameo as John Barrowman's daughter in the 50th anniversary spoof, The Five(ish) Doctors Reboot.

As well as Olive, David and Georgia are parents to share Ty, 19, Wilfred, eight, six-year-old Doris and Birdie, who turns two in October.
