Helena Bonham-Carter dons a brown wig as she films upcoming Holocaust drama One Life in Hampstead 

Helena Bonham Carter looked very different from her quirky self as she filmed scenes for her upcoming drama, One Life on Tuesday.

The 56-year-old actress wore a curly brunette wig as she dressed up as she enjoyed a coffee break on set in Hampstead.

The BAFTA winner joins two-time Oscar winner Anthony Hopkins and Johnny Flynn in the feature film drama set during the Holocaust.

The production is inspired by the true story of Nicholas Winton – a London stockbroker who devised an elaborate plan to save hundreds of children in Czechoslovakia from invading Nazis.

The title is paraphrased from the Jewish Talmud: “Whoever saves one life saves the whole world.”

Helena plays Winton’s mother Babi Winton, who was of German Jewish descent but had settled in north-west London with her husband.

Nicholas Winton’s story recently went viral when a YouTube clip revealed a 1988 episode of the BBC’s That’s Life, when Esther Rantzen presented a special edition featuring him.

During the broadcast, the TV host, 82, asked, ‘Is there anyone in our audience who owes their life to Nicholas Winton? If so, could you please stand up?’

Everyone in the studio audience stood up and the episode has been viewed many millions of times on You Tube.

Jonathan Pryce, Romola Garai and Alex Sharp will also star in the drama, but no release date has been announced yet.
