LATEST: English film-maker Gurinder Chadha is in talks to direct the movie adaptation of 1980s soap opera DALLAS - a week after Robert Luketic walked out on the project. Luketic abruptly quit the 20th Century Fox-produced movie last week (ends31MAR06) amid reports he was unhappy with the casting choices. Jennifer Lopez, Shirley Maclaine, John Travolta and Luke Wilson are currently in negotiations to play SUE ELLEN, MISS ELLIE, JR and BOBBY EWING respectively. Kenyan-born Chadha is known for her work on Bend It Like Beckham, WHAT'S COOKING? and BRIDE AND PREJUDICE.
