To celebrate Mass Effect’s 10th anniversary (crikey!), animator Jonathan Cooper, currently at Naughty Dog, has shared 10 animation-related facts about the game on Twitter. There are a lot of interesting titbits, like the mo-cap being filmed on the same sound stage as Gone With The Wind, or Cooper being inspired by Ricky Gervais’ Extras when it came to picking the close-up camera style for conversations, but nothing beats the story behind Anderson punching Udina in the face. Udina was a worm, so it’s a popular scene, but probably not with the actor playing Udina. He actually got clocked on the jaw. It happens to the best of us.
