What's on TV

Friday 7/4

Boston Pops Fireworks Spectacular (CBS, 10 p.m.): From the Charles River Esplanade, fireworks explode as the Boston Pops play the 1812 Overture. LeAnn Rimes and the Mormon Tabernacle Choir also perform.

Tour de France (Outdoor Life Network, 9 a.m.) Live coverage of the European bike race. Will Lance Armstrong win a fifth title?

The Directors: James Ivory (Encore, 11-12 p.m.): The American director, half of the Merchant-Ivory team (producer Ismail Merchant is Indian) talks about his passion for filmmaking. We also hear from actors such as Joanne Woodward and Anthony Hopkins. We may know Ivory best for films like "The Remains of the Day" and "A Room With a View," but he also worked on Indian stories like "Shakespeare Wallah" (about a troop of British and Indian actors who travel India).

This Week With George Stephanopoulos (ABC, check local listings): Stephanopoulos will sit down with Supreme Court justices Sandra Day O'Connor and Stephen Breyer in Philadelphia to discuss the opening of the National Constitution Center. The interview will focus on the relevance of the Constitution today, as well as the recent controversial court decisions.

Mystery! (PBS, 9-11 p.m.): The new season premières with "Dead Gorgeous" - a black comedy about two women encumbered by husbands who are, to say the least, inconvenient. Think Hitchcock's "Strangers on a Train," but this story is funnier and bleaker than Hitchcock's. TV-PG

Discovering Dominga (PBS, 9 p.m., check local listings): Another in the P.O.V. series, this story concerns a 27-year-old Iowa housewife who returns to her native Guatemala and to her long-lost family - what is left of it. She was taken to America at age 9 after most of her immediate family were massacred, victims of genocide. This quietly demanding film probes why these innocent Mayans were murdered.

Tribute to Katharine Hepburn (Turner Classic Movies, 6 a.m., check local listings): TCM kicks off its 24-hour tribute with the 1936 film "Mary of Scotland."
