Daniel Radcliffe to star in Who Do You Think You Are?

Daniel Radcliffe is to feature on \'Who Do you Think You Are?\'

The \'Harry Potter\' actor will delve into his past on the BBC genealogy show to look into the story of his great-great-uncle Ernie who fought at World War I.

A source told The Sun newspaper\'s Bizarre TV column: "When Daniel starred in TV drama \'My Boy Jack\' - one of his first major roles after Potter - his inspiration was his great-great-uncle Ernie, who lost his life in World War I.

The first trailer for 'LEE', starring Kate Winslet is here.

"As Daniel investigates exactly what happened to Ernie during the war, he discovers an extraordinary and moving cache of letters Ernie wrote home.

"He pieces together the heart-breaking story of how Ernie fought alongside his three brothers and how all of them, except for Ernie, survived."

It comes just a month after Kate Winslet was also said to have signed up to the series to explore her past.

She is said to have been in the UK filming her episode already for the 16th series of the popular programme.

An insider recently explained: "Getting a bona fide film star to take part in \'Who Do You Think You Are?\' is a real coup for the makers of the show.

"There\'s only been a handful of participants on a similar level, such as Sir Ian McKellen and JK Rowling, and she\'s likely to top the bill of names in the new series.

"The programme continues to be one of the most popular shows on the Beeb and signing up genuine stars is proof of its ongoing appeal."

The episode is likely to delve into her maternal grandfather, who got divorced and remarried - which was a huge scandal at the time in 1938.

He also married a woman 17 years younger while another of Kate\'s relatives, Robert Bridges, married his own cousin - nine years his junior - in 1851.
