My Grandparents’ War sees Helena alongside fellow actresses Kristin Scott Thomas, 59, and Carey Mulligan, 34, travelling the world to meet survivors from the Second World War. 

The stars’ grandparents all served in the conflict but rarely spoke about the war and the impact which it had on them.

And so they learn about experiences on the beaches of Dunkirk, in prisoner of war camps in the Far East and the life and death decisions which their relatives had to make.   

The show’s executive producer Tom Anstiss said: ‘Many of our grandparents served in the war, and the vast majority of them didn’t feel as though they could talk about it when they returned home.’   

‘These actors had intimate and loving relationships with their grandparents but have a host of unanswered questions.’

Prior to her romance with Rye, Helena was previously in a long-term relationship with Hollywood director Tim Burton from 2001 until 2014.

The pair famously lived in two adjourning houses in London during their relationship, and Helena was one of his favourite muses to cast in his dark fantasy films.

They have two children together, a son called Billy Raymond and a daughter named Nell.
