James Brolin and Diane Ladd are in negotiations to play EWING family parents JOCK and MISS ELLIE in the revamped Dallas movie project. Directors and cast quit the film at the beginning of 2007, leaving signed-up star Luke Wilson to comment he felt the film adaptation of the 1980s TV soap would never be made. Wilson is reportedly still onboard, as is John Travolta, who has been cast as oil tycoon villain J.R. Ewing - and now a few more gaps are being filled, with Dr Doolittle director Betty Thomas at the helm. According to website CinemaBlend.com, Brolin has already agreed to play the part of Jock Ewing, the role played by the late Jim Davis in the TV series. Minka Kelly is reportedly in talks to replace Jennifer Lopez as Pamela Ewing, while Julie Bentz has been offered the part of J.R.'s wife Sue Ellen Ewing.
