Dreamgirls' Jennifer Hudson and comeback kid Eddie Murphy, Dame Helen Mirren and Oscars host Ellen DeGeneres will sit down for the 26th edition of The Barbara Walters Special, airing Sunday, Feb. 25, at 7 pm/ET (and immediately following the kudoscast for West Coasters).

In the Oscar Night Q&As, Hudson says that if she had won Idol, she probably would have never gotten the role of Effie; Mirren talks about disrobing on camera; Murphy shares what winning an Oscar would mean to him; and DeGeneres discusses her plan to differentiate herself from past hosts.
