Wilde was apparently one of Marvel's top picks to play Gamora — she was even offered the role! In the end, she turned it down, most likely out of exhaustion with playing similar roles for years.
"People thought I could only play the badass so I'd always get those roles. It just doesn't feel very human. I got cast as a computer program in Tron: Legacy and an alien in Cowboys and Aliens. I was, like, 'There's something wrong here …'," she admitted to the Guardian in 2013, likely explaining, indirectly, her reasons for passing on Gamora.
