Angelina Jolie took ballet lessons for her role as Thena in The Eternals. This helps her to bring out a feminine touch to her strong character.
She explained, “I trained in ballet because I watched the other Marvel films, and everybody [has ] just done such an amazing job. I wanted to try to bring something different to Thena, and I thought to make her as female as long and soft.”
“Because as written, she’s the strongest fighter, she’s the toughest. So I countered it. I tried not to think about that…I tried to make as graceful as I could, not as strong.”
Apart from that, she also had to learn to use a various number of weapons.
