Veteran British actress Jean Lodge, whose glamorous screen career stretched back to the golden age of postwar cinema and whose family became a television dynasty, has died at 99.

Lodge, best remembered for playing Queen Guinevere in the 1954 adventure movie The Black Knight, died Wednesday, according to The Hollywood Reporter.

Her death came just one day after her Aug. 4 birthday, her granddaughter Amy Shaughnessy announced.

Born Jean Margaret Lodge in Hull, Yorkshire, England, in 1927, Lodge began her acting career on the stage with the Windsor Repertory Company before making the leap to movies in 1949.

That year, she appeared in Dick Barton Strikes Back and Dr. Morelle: The Case of the Missing Heiress, beginning a film career that would span decades.

Her biggest role came in The Black Knight, where she portrayed King Arthur’s legendary wife, Queen Guinevere, opposite Hollywood star Alan Ladd and future horror icon Peter Cushing.

Lodge also appeared in White Corridors in 1951, Brandy for the Parson in 1952, Final Appointment in 1954 and the 1966 sci-fi film Invasion.

But her influence in the entertainment world extended far beyond her own acting career.

In 1948, Lodge married acclaimed screenwriter Alfred Shaughnessy, who would later become the developer and head writer of the hugely successful British television drama Upstairs, Downstairs.

Shaughnessy, a two-time Emmy nominee, remained married to Lodge until his death in 2005.

Their two sons also went on to major careers in television.

Charles Shaughnessy became a household name in the U.S. as charming Broadway producer Maxwell Sheffield opposite Fran Drescher on the hit sitcom The Nanny. He also became a longtime soap favorite playing Shane Donovan on Days of Our Lives.

Their other son, David Shaughnessy, built his own successful career behind the scenes, working as a producer on The Young and the Restless and a director on The Bold and the Beautiful.

Lodge’s granddaughter Amy remembered the actress as a larger-than-life presence whose energy never seemed to fade.

“My grandmother was a beautiful, talented, complicated, passionate, emotional, energetic woman who was always on the move and full of life,” she wrote.

Amy also described Lodge as the “perfect hostess” and said she had passions well beyond acting, including theater, gardening and painting.

She called her grandmother an “amazing artist.”

Lodge leaves behind sons Charles and David, granddaughters Amy, Jenny, Katie, Maddy and Josie, and great-grandsons Julian and Noa.

Her death closes the chapter on a nearly century-long life that touched British cinema, classic television and several generations of one of entertainment’s most accomplished families.
