London calling: Summer Olympics begin Mark Humphrey / AP Michael Phelps will once again be an Olympian to watch. Your TVs are about to be taken over. The Summer Olympics begin this week, with athletes from all over the world gathering in London to go for the gold. It's by far the biggest event of a fairly quiet summer week, and it's the gift that keeps on giving, as there will eventually be 5,500 hours of coverage spread over NBC's various platforms. Watch all that and you deserve your own gold medal. TUESDAY: 'Game of Thrones' season one Maybe you don't have HBO, but you've read the books, or heard about them, and are itching to see "Game of Thrones" presented onscreen. Or maybe you did catch the first season, but need a refresher. The much-acclaimed fantasy series based on George R.R. Martin's books has aired two seasons on premium cable, and now the first season is coming to home video. Don't lose your head running to pick up your own copy. Whoops, was that a spoiler? On DVD and Blu-ray July 24. FRIDAY: Summer Olympics opening ceremony Whether your favorite summer Olympic sport is swimming, gymnastics, track, volleyball or any of the dozens of other offerings, prepare to make a you-shaped dent in the nearest couch. The opening ceremony of the London Olympics is this week, and the games will roll on through Aug. 12. This week's opening ceremonies promise to pull out all the stops as far as British pomp and circumstance, with the Queen and Prince Philip officially opening the Games. Names to watch once the competition begin include American swimmer Michael Phelps, Jamaican runner Usain Bolt, American runner Tyson Gay and American runner Lolo Jones. Find your favorite athlete, sport, and when it airs on NBCOlympics.com. Opening ceremonies July 27, 7:30 p.m., NBC. FRIDAY: 'The Watch' The movie "The Watch" earned some uncomfortable attention earlier this year, when its title was changed from "Neighborhood Watch" to avoid association with the shooting of Trayvon Martin by neighborhood watch captain George Zimmerman in Florida. The film itself is a comedy, with Ben Stiller, Vince Vaughn, Jonah Hill and Richard Ayoade as neighbors who stumble on an alien plot. Can it overcome the odd events that necessitated its title change? Opens July 27.
