Jennifer Lopez has quit the big screen remake of classic 1970s show Dallas.
Jennifer Lopez was set to star opposite John Travolta, who will play JR Ewing, as his alcoholic wife Sue Ellen.
Shirley MacLaine is in talks to star as Ewing family matriarch Miss Ellie and Luke Wilson is rumored to be taking on the role of Bobby Ewing.
Jennifer Lopez's rep Leslie Sloane Zelnick has confirmed to American publication Star:
She is out of Dallas. 
The role of Lucy Ewing has also been the subject of much speculation, with many of Hollywood's top young actresses vying for the part including Jessica Simpson, Lindsay Lohan and Kristin Cavallari. The role ultimately went to 19-year-old Katie Cassidy, who stars in the US family drama 7th Heaven.
