Joan Van Ark has said she wanted to honour her iconic character Valene when she returned in the new Dallas.
Joan, 69, played Valene Ewing in the Dallas spin-off Knots Landing which started 34 years ago.
The actress returned to TV screens recently with a guest spot in the new series of Dallas on Channel 5 as her old alias.
She said: "I wanted to honour Valene. I wanted to be sure I was delivering Valene and how she might look and how she might be 20 years later, and how she would react to people, and that includes with Charlene Tilton, who plays my daughter, and most importantly, with Val's husband Gary, played by Ted Shackelford.
"Val was difficult sometimes, she was tough to live with, tough to play, but I loved every golden moment."
:: Knots Landing begins on CBS Drama on Monday, April 1 at 11pm.
