THE WILLIAMS SISTERS OF THE U.S. HOLD THEIR TROPHIES AFTER WOMEN'S SINGLES FINAL AT WIMBLEDONBefore they were born, Venus and Serena Williams’ dad had a 78-page plan on how they’d each become No. 1 in tennis. The two sisters from Compton followed through and their story to glory is told in the documentary “Venus and Serna” (Showtime, 9 p.m.). The film by Maiken Baird and Michelle Major follows them from youth to the 2011 season, when injuries began taking their toll.

In another original film tonight, “Forever 16” (Lifetime Movie Network, 8 p.m.), Tiera Skovbke stars as a teenager who has to keep switching high school to keep her timeless secret.

The march to the 50th anniversary of the March on Washington begins with a couple of cable documentaries, “March on Washington: The Dream Continues” (MSNBC, 6 p.m.), with the Rev. Al Sharpton, Martin Luther King III and Bernice King. Later, Don Lemon hosts “We Were There: The March on Washington — An Oral History” (CNN, 10 p.m.) which features the only survivor of the main six organizations who spoke in 1963, Rep. John Lewis of Georgia.

The big ratings winner tonight will likely be the network NFL preseason game of Seattle at Green Bay (CBS, 8 p.m.).

The special “The Last Huntsman” (Discovery, 10 p.m.) follows people who try to keep the wild away from people, such as a guy in Alaska who tries to keep a bear from a mining camp, or one who tries to kep a jaguar from a Peruvian logging camp. Not to be confused with “Snow Whie and the Huntsman” (HBO, 6:45 p.m.).

More bad taste from “America’s Next Top Model” (The CW, 9 p.m.), with a trailer park chic photo shoot.

Want to catch up on the week’s “Big Brother” (TV Guide Network, 8 p.m.)? It’s on all night on cable. There are other catchups for “Boardwalk Empire” (HBO, 9 and 10 p.m.).

With the writers on strike, maybe we shouldn’t cross the picket line to watch “Fashion Police” (E!, 9 and 10 p.m.).

In honor of Whitey Bulger’s conviction, “The Departed” (AMC, 8 p.m.).

No Conan O’Brien on tonight, but there is “Conan the Barbarian” (BBC America, 9 p.m.).

Elizabeth Taylor, from child to woman, stars on Turner Classic Movies all day with “Lassie Came Home” (7:15 a.m.), “National Velvet” (8:45 a.m.), “Life with Father” (11 a.m.), “Father of the Bride” (1 p.m.), “Father’s Little Dividend” (2:45 p.m.), “Giant” (4:15 p.m.), “Cat on a Hot Tin Roof” (8 p.m.),”Suddenly, Last Summer” ( 10 p.m.), “Who’s Afraid of Virginia Woolf?” (midnight), “Reflections in a Golden Eye” (2:30 p.m.) and “Conspirator” (4:30 a.m.).
