Oscar-winning actress Judi Dench will appear on an October episode of the genealogy docu-series, Who Do You Think You Are? the BBC announced Monday.

The 86-year-old Shakespeare in Love and The Best Exotic Marigold Hotel star will explore her family's roots in Denmark and her British father's experiences fighting in World War I.

Other well-known figures who will participate in the show this season are Ed Balls, Pixie Lott, Joe Lycett, Alex Scott, Joe Sugg and Josh Widdicombe.

"Who Do You Think You Are? is back with another line-up of Britain's best-loved celebrities exploring their family histories across the United Kingdom, Ireland, Denmark and Jamaica. The incredible personal stories they unearth of their ancestors' lives -- from royal love triangles to laborers fighting for their rights, from Victorian child sweeps to battling fascists in London's East end -- reflect and illuminate all our collective history," executive producer Colette Flight said in a statement.
