Teenage Mutant Ninja Turtles Out of the Shadows is in cinemas now and while you can probably see that a lot of CG work goes into bringing those characters come to life, a surprising amount of their performances come from real actors on set.
You can see how the technology was used in this behind the scene video which shows the four actors suited up in costumes that include shells on their backs, for full live location shooting on the streets of New York city.
The use of the technology is pretty fascinating, and only a few years after it was all studio bound with the likes of the original Lord of the Rings films or Avatar. And the facial performances are hugely impressive. We've come a long way from Jar Jar Binks.
