Tom Brokaw and the “NBC Nightly News” will have a new look this week--at least for some viewers. The show will begin appearing with closed captions to enable the deaf and hearing-impaired to understand what is being said. The captions will be seen only by those viewers who have purchased special decoding devices that attach to the TV set.

Sam Waterston, who stars on CBS this month in “Terrorist on Trial,” will be seen later this season in another major TV movie, “Gore Vidal’s Lincoln,” playing Abraham Lincoln from his inauguration as the 16th President in January, 1861, through his assassination in 1865. Mary Tyler Moore has been cast as Mary Lincoln in the four-hour drama for NBC.

Jack Paar, who returned to TV in a prime-time special last season, will star in another such show for NBC this season. His guests on “Jack Paar Is Alive and Well” will be Debbie Reynolds, Jackie Mason and George Burns. The program is set to air Dec. 19.
