The voluptuous Catherine Zeta-Jones is to play the wholesome Pamela Ewing while her Ocean’s Twelve co-star Brad Pitt is also expected to join her in the movie, which begins filming later this year.

Screenwriter Robert Harling says he has been working for 18 months on the Dallas script which features the original characters from the pilot of the 1978-1991 series.

“It’s reinventing the Ewing family as if they existed now in 2006 when the movie comes out. The characters are outrageous - one of the things I told the studio is ‘I’d like to do Dallas on acid’.”
