Live streaming or tape-delayed to prime time, we're watching the Summer Olympics, but there's a lot more to check out this week than just the action in Rio. The highly-anticipated game No Man's Sky arrives on PS4 and PC this week, allowing gamers to visit some 18 quintillion planets in a quasi-multiplayer game. On Netflix, The Get Down revisits the birth of hip-hop with its first six episodes, and The Walking Dead crew gets together to preview season seven. On Blu-ray the Japanese series Female Prisoner Scorpion is arriving, and Oblivion is out on Ultra HD Blu-ray with a Dolby Atmos audio track. Look after the break to check out each day's highlights, including trailers and let us know what you think (or what we missed).
