Veteran actresses Deborah Shelton and Cathy Podewell - who played J.R. Ewing's long-term mistress Mandy Winger and his second wife Cally Harper in the original run of TV hit Dallas - will make a dramatic return to the show in March (13) at the backstabbing oil baron's funeral. The character will be killed off following Larry Hagman's death from cancer in November (12).
