Walter Cronkite will be back on the...

Walter Cronkite will be back on the air March 31 with an hourlong special, “Walter Cronkite at Large.” The former CBS news anchor visits the Centers for Disease Control in Atlanta, interviews foreign policy expert George Kennan, and reports on the search for treasure aboard a sunken pirate ship.

The next “Perry Mason” movie is in the works, with Raymond Burr back as the famed defense attorney. Due for telecast this spring, it will be called “The Case of the Sinister Spirit” and will co-star Robert Stack, Dwight Schultz, Leigh Taylor-Young, Kim Delaney and Jack Bannon.

CBS has set April 5 as the telecast date for a revival of “Crazy Like a Fox.” The series was canceled by CBS last season but the producers persuaded the network to let them demonstrate that the show still has legs by airing this two-hour installment, “Still Crazy Like a Fox.” Jack Warden and John Rubinstein star as father and son, this time on the job in England.

Also coming April 5 is ABC’s “Daddy,” a provocative new TV film about two teen-agers who become parents. The movie is intended to give young viewers information about dealing with their sexuality. Dermot Mulroney and Patricia Arquette play the film’s young lovers.

Robert Conrad’s real-life sons will portray his fictional sons in “High Mountain Rangers,” a TV movie that is being made for CBS. The movie is very much a family affair: besides co-starring Christian Conrad and Shane Conrad, the senior Conrad is its director and co-writer (with David J. Kinghorn). Joan Conrad, his daughter, is the executive producer.

A lawyer’s obligation to treat his client’s private comments as privileged information forms the framework for a new ABC movie with Peter Coyote and Dabney Coleman. In the film, “Privileged Information,” they play attorneys who take up the defense of an unseemly man accused of murder, only to have him confess to them privately that he is guilty.

You loved her in “The Sound of Music,” now catch her in “The Sound of Christmas.” Notwithstanding the fact that the yuletide holiday is nine months away, ABC has signed Julie Andrews to star in a Christmas special that will be taped on location in Europe.
