full size Grey's Anatomy Season 9 Promo Pics: Jessica Capshaw (Arizona Robbins)

Arizona (Jessica Capshaw) is finally up on her feet, both literally and figuratively on Grey's Anatomy. But in a more literal sense, we’re most curious about how they make it look like Jessica Capshaw only has one leg. 

Apparently, a lot of people have been wondering the same thing, because Jessica tweeted the secret to their television magic: “In [Season 9, Episode 6: “Second Opinion”] I was walking on a prosthetic with my own leg tied behind me. Starworks digitally erased any overlap. They are amazing!”

That does not sound comfortable, but it did look amazing! Are you surprised at how good the final product turned out? What do you think is Grey’s Anatomy’s most impressive digital effect in the show’s history?
