Elizabeth Olsen and Aaron Taylor-Johnson consulted each other before accepting their roles in 'Avengers: Age of Ultron'.
The 26-year-old actress and the 24-year-old actor - who plays her on-screen twin brother - didn't accept their roles of Wanda and Pietro Maximoff until they had spoken to each other, having just finished working together on 'Godzilla'.
Elizabeth said: "Aaron and I had just finished working with each other and we both got roles, so we were like, 'Are you going to do it?' 'Are YOU going to do it?' 'Let's do it.'
"It was awesome working with him a second time. I love him and his wife Sam (Taylor-Johnson), and spent lots of time with them when we were shooting in London."
Younger sister to Mary-Kate and Ashley Olsen, both 29, Elizabeth has continues to star in Hollywood blockbuster films whilst her sisters are more focused on their fashion careers.
Speaking about her twins to Stella magazine, Elizabeth said: "It's just crazy. They've never had a year off in their whole lives.
"They're amazing, diligent, kind, beautiful, hard-working women who have tons of responsibility and are great at what they do."
