Walter Cronkite's voice is about to disappear from the CBS Evening News, nearly six months after his death.

Starting Monday, actor Morgan Freeman will introduce anchor Katie Couric.

Freeman, with his own distinctly recognizable, deep, authoritative voice, has done voice work on films such as March of the Penguins and The Love Guru.

His voiceover replaces one that Cronkite recorded in 2006, when Couric took over as anchor of the Evening News.

Cronkite, a former anchor often referred to as "the most trusted man in America," died July 17, 2009, at age 92. He had retired as anchor at 65 in 1981 but continued to do reports for CBS and other networks.

However, CBS left his voice on air, replacing it only when Couric was to give special reports.

"As comforting as it is to look back on the great career that Walter had, we're looking forward now, and we just felt it was the right time to make the move that at some point had to be made," said CBS News and Sports president Sean McManus.

"This seemed like the appropriate time since Walter's passing to make the move."
