A Dartmoor Hill pony foal runs on the moor on Dartmoor on May 17, 2011 in Princetown England. Although a tourist attraction, especially during the foaling season and often seen as part of the landscape of Dartmoor, many ponies face an uncertain future due to unsustainable breeding and their falling market values. The charity South West Equine Protection estimates that last year 1500 ponies were slaughtered – with many being sold for lion meat to nearby zoos. Along with other equine charities, they are calling for the removal of stallions from the moor to bring numbers down to sustainable levels. (Photo by Matt Cardy/Getty Images)

The American, Walter James Palmer, a Minnesota dentist who paid $50,000 to kill the lion, has left Zimbabwe. He says he did kill the animal but believed the hunt was legal and that the necessary permits had been issued. (Photo by Eric Miller/Reuters)

The characters fighting for Westeros in Game of Thrones are fighting mostly for CGI backdrops. Like many others TV series and movies, visual effects is a huge part of the production process as it handles details both great and small. A great credit to Game of Thrones is that the story is so good that we forget about the effects, and another great credit goes to the VFX team because their work is seamless. If you want to see the seams, you have to get a visual breakdown of how the shots are put together.
