Victoria Principal Will Not Appear On TNT’s DALLAS

Victoria Principal has issued a statement to Deadline about why she will not return to the role of Pamela Barnes Ewing on DALLAS
“Since the inception of ‘Dallas’, the creators and fans around the world have referred to Bobby and Pam, as the Romeo & Juliet of ‘Dallas’. I could not agree more. And since the original author of this scenario, William Shakespeare, felt compelled to make theirs a tragic love story, of epic and unforgettable deathly loss, I think I shall respect that very successful example, and leave the legacy of Bobby & Pam’s tragic love story, undisturbed and intact.

When I filmed Pam’s fatal car accident, for me that was the punctuation mark on my role as Pam. I cannot be held responsible for any choices made by producers, once I left ‘Dallas’, but I do take responsibility for my decision, not to risk tarnishing Bobby & Pam’s love story, with a desperate reappearance. I made this decision a long time ago with a loving and respectful heart for ‘Dallas’, Bobby & Pam and all faithful fans.”
TVLine reported in December that Principal was on the DALLAS producers' return wish list.

Showrunner Cynthia Cidre previously claimed that the character of Pam was unlikely to return to the show, arguing that TNT's revamp "needed a breath of fresh air".
