Kate O'Mara, 74, a British actress best known for her role as Caress Morrell, sister to Joan Collins' Alexis Colby, in the 1980s prime-time soap opera "Dynasty," died Sunday at a nursing home in southern England after a short illness, according to her agent, Phil Belfield.

The actress, who began her television career in the 1960s, is remembered by many for her role in "Triangle" — a soap opera set aboard a North Sea ferry that is often cited as the worst piece of British television.

She also appeared in the original run of the British series "Doctor Who" and the BBC drama "Howards' Way." In the 1990s she starred with Joanna Lumley in the comedy show "Absolutely Fabulous."

More recently she appeared in a 2012 stage adaptation of Agatha Christie's "Death on the Nile."

Born Aug. 10, 1939, in Leicester, England, O'Mara had a sister, Belinda Carroll, who also became an actress.
