Terror-at-the-Mall-Movie-Still-2The shocking terrorist attack on a modern shopping mall in Kenya that killed 71 last year — a year ago this week as a matter of fact — is relived through the most stark of footage: from more than 100 security cameras. Recollections of survivors on site and some of their cell phone coverage also help tell the alarming story in the documentary “Terror at the Mall” (HBO, 9 p.m.).

The banality of the setting and the abject fear of those who happened to be there led to some compelling examples of bravery and leadership under (literal) fire.

The biggest documentary continues to sail like an unstoppable barge — the second two hours of “The Roosevelts” (PBS, 8 and 10 p.m.) moves into the 20th century, with its own shocking use of violence — the assassination of William McKinley leading to Theodore Roosevelt’s ascension to the presidency. Also, Franklin marries Eleanor and runs for the New York state senate.

The least appealing group of celebrities yet are assembled for the 19th (!) round of “Dancing with the Stars” (ABC, 8 p.m.), where the judges panel is expanded to include an ex-pro on the show, Julianne Hough, who may be more famous than most people on the floor. Among them: Tommy Chong, Betsey Johnson, Lea Thompson, Alfonso Riberio and Tavis Smiley. The season premiere runs two hours.

Two other reality shows name winners. “American Ninja Warrior” (NBC, 8 p.m.) takes three hours to close its unending summer season; a winner is crowed to close the fifth season of “MasterChef” (Fox, 8 p.m.), winning $100,000.

Turner Classic Movies begins a 24 hour salute to Lauren Bacalll who died Aug. 12 at 89 with a number of her greatest films beginning with a 2005 interview, “Private Screenings: Lauren Bacall” (8 p.m. and 2:45 a.m.) plus her unforgettable bow in “To Have and Have Not” (9 p.m.), “The Big Sleep” (11 p.m.), as well as “How to Marry a Millionaire” (1 a.m.) and “Harper” (3:45 a.m.). It concludes Tuesday, which would have been her 90th birthday.

As if to get ready for his fall sitcom on ABC, the host of “Eating America with Anthony Anderson” (Food Network, 10:30 p.m.) ends his season of travel and treats with a stop at the Rockwood Ice Cream Festival in Delaware.

It’s Eagles at Colts (ESPN, 8:15 p.m.) on Monday Night Football.

A new coast is found for “Love & Hip Hop: Hollywood” (VH1, 8 p.m.) with Soulja Boy, Omarian and Ray J — and their women — are among the subjects.

“The Approval Matrix” (Sundance, 11 p.m.) ends its short, ineffectual run.
