Glenda Jackson, who earned the Triple Crown of acting during her career, has died at age 87.

She died Thursday at her home in London after a short illness, according to her agent, Lionel Larner.

He also said she had recently completed filming "The Great Escaper," co-starring with 90-year-old Michael Caine, with whom she had previously starred with in 1975’s "The Romantic Englishwoman."

Caine said it was "as wonderful an experience this time as it was 50 years ago," when the two last worked together.

"Glenda was one of our greatest movie actresses," he said. "I shall miss her."

Jackson was born into a working-class family in Birkhenhead, northwest England, in 1936, and later trained at the Royal Academy of Dramatic Art in London. She performed with the Royal Shakespeare Company and starred in the cutting-edge drama "Marat/Sade" directed by Peter Brook.

She became one of the top British stars in the 1960s and '70s with films like "Mary, Queen of Scots," "Sunday Bloody Sunday" and "The Class of Miss MacMichael."
