Actor Amanda Seyfried says she turned down a major Marvel Cinematic Universe role because she didn't want to be tied to a specific role for a large portion of her career.
“I turned down [a Marvel Studios movie] once and they haven’t called back since,” Seyfried told MTV. “And it was a big’un. I don’t regret it because I didn’t want to be green for six months out of every year. They tell beautiful stories through superheroes, and my daughter’s now really obsessed with superheroes now, and part of me wishes I’d done it, but the other part of me is like ‘I had a life to live’ and I don’t think I would’ve been happy.”

Seyfried's comment about not wanting to be "green" implies that the role was Guardians of the Galaxy's Gamora (a role eventually played by Zoe Saldana) who has green skin - though it's possible she meant it as a figure of speech, or could have been referring to a different green-skinned character that didn't come to fruition.
