A fascinating series of reveals, showing the use of green screens to add backgrounds to telly programmes.

Call me naïve, but I had no idea so much ‘location’ shooting was done in the studio, when there’s no need (as there would be in a sci-fi show, say, for special effects or outlandish scenery).

Presumably it won’t be long before it’s cheaper to do away with sets and locations entirely, and build everything that’s not an actor inside a computer.

Via Holy Moly, of all places.
