The battle of the Alamo will be fought again on NBC Jan. 26. Starring in the three-hour “The Alamo: 13 Days to Glory” are James Arness as Jim Bowie, Brian Keith as Davy Crockett, Lorne Greene as Sam Houston and Raul Julia as Gen. Santa Anna.

The next “Hallmark Hall of Fame” presentation will be “The Room Upstairs,” set to air on CBS Jan. 31. It stars Stockard Channing as a lonely woman who runs a boarding house. Sam Waterston portrays one of her boarders, who helps bring her out of her shell, and Linda Hunt co-stars as Channing’s supervisor at work.

Public-television viewers will see Sam Waterston three days earlier, when he hosts “Generation at Risk,” an hourlong PBS special that reports on how several communities have successfully addressed problems faced by their teen-agers. It’s a follow-up to the 1983 program “The Chemical People,” about drug and alcohol abuse among teens.

Ann Jillian has the lead role in “Convicted: A Mother’s Story,” a TV movie scheduled for broadcast Feb. 2 on NBC. She plays a woman who must try to keep her family together while serving a prison sentence. Kiel Martin of “Hill Street Blues” portrays her boyfriend and Gloria Loring of “Days of Our Lives” plays her sister.

“I’ll Take Manhattan,” CBS’ eight-hour adaptation of the novel by Judith Krantz, will be broadcast March 1-4. Valerie Bertinelli stars as a woman trying to hold together her father’s magazine empire. Other stars include Barry Bostwick, Francesca Annis, Jane Kaczmarek and Jack Scalia.

Jim Henson is going to produce another cartoon series for Saturday mornings. He’s already represented on CBS by “Muppet Babies,” and starting next fall he’ll have an animated series on NBC based on “Fraggle Rock,” the Muppet-type show that Henson does for Home Box Office.
