The weekend's highlights:

The next "Breaking Bad" arrives at 9 p.m. Sunday on AMC. In the cryptic preview, Walt (Bryan Cranston) says he has a bad feeling. AMC offers this preview of the episode titled "To'hajille": "Things heat up for Walt in unexpected ways." The series ends its closely examined run Sept. 29.

"Dexter" is back at full viewing force after a fight over fees ended between CBS Corp. and some cable providers. The next episode, "Goodbye Miami," airs at 9 p.m. Sunday.

"Boardwalk Empire" starts its new season at 9 p.m. Sunday on HBO. But all the dramas are likely to be dwarfed in the ratings by "Sunday Night Football" on NBC. The New York Giants play the Dallas Cowboys at 8:30 p.m. Sunday.

Derek Jacobi will always be cherished for "I, Claudius," and fans get another to see him in "Last Tango in Halifax" at 8 p.m. Sunday on PBS. Do not think that title suggests racy viewing. "Halifax" focuses on childhood sweethearts who are reunited in their 70s. Both are widowed, and they fall in love all over again. Jacobi and Anne Reid headline the six-part series, a huge hit in Great Britain. The finale of "Silk" follows at 9 p.m. Sunday on PBS' "Masterpiece Mystery!"

Queen Latifah salutes educators in "Teach," a CBS special from 8 to 10 p.m. Friday. The network says the special "captures the essence of what it means to be a teacher through the lens and extensive footage of a year-in-the-life of four public school teachers in Denver, Los Angeles and Kuna, Idaho." The special also features Jon Cryer, Joseph Gordon-Levitt, Rashida Jones, Jerry O'Connell and Anna Faris.

The Rev. Al Sharpton hosts "Advancing the Dream: Live from the Apollo" at 8 p.m. Friday on MSNBC. His guests include Stevie Wonder, Tyler Perry, Magic Johnson, Cathy Hughes and Condoleezza Rice. They meet at the Apollo Theater in Harlem to discuss workers' rights, income inequality, education and the modern-day civil rights movement.

In news, "Dateline NBC" focuses on three young people determined to scale Mount Everest at 9 p.m. Friday. ABC's "20/20" starts a new season by telling the story of an Alabama chiropractor who has been married six times, and wife No. 5 died unexpectedly. The program starts at 10 p.m. Friday.

And "PBS NewsHour" expands to the weekends. It will air at 6:30 p.m. Saturdays and Sundays, starting this weekend, on WUCF-Channel 24.
