It's Mike Wallace's turn to answer the questions when his 60 Minutes colleagues put the spotlight on him and his incredible body of work for his last regular appearance on CBS News. "I'm Mike Wallace: a 60 Minutes Tribute" will be broadcast on Sunday May 21 (7:00-8:00 PM, ET/PT) on the CBS Television Network.

60 Minutes correspondents expose the inner Wallace few have ever seen, asking him the impertinent, the probing questions -- the kinds of questions he has used to make interview subjects squirm for decades. The retrospective of Wallace's life also includes rare footage from the early career of a legend who has appeared regularly on television every year since 1949.

The hour will reprise some of his most controversial and engaging interviews, including the Ayatollah Khomeini, Johnny Carson, Zhang Zemin, Mel Brooks, Vladimir Putin and Barbra Streisand.

Wallace, who turns 88 on May 9, announced in March that he would retire from regularly scheduled appearances. He becomes a CBS News correspondent emeritus at season's end, appearing occasionally on CBS News programs.
