In the following years, Söderlund collaborated with many renowned directors, such as Gabriel Axel, Jan Troell, Stanley Kubrick, and Hans Alfredson, among others. In particular, her meticulous work on Troell's 1971 historical drama The Emigrants as well as its 1972 sequel, The New Land, garnered a great deal of attention and launched her to international prominence. Along with other career prospects, she and Milena Canonero worked together on the authentic 18th-century wardrobes for Kubrick's 1975 epic Barry Lyndon. That ambitious project required a year and a half of preparing the costumes, studying paintings, and reading books to reproduce garments for the screen. Their remarkable efforts received critical and audience admiration, ultimately winning them the Academy Award for Best Costume Design. Söderlund was the first Swedish designer ever to win in the category.[1]
In the late 1970s, Söderlund worked on the acclaimed Danish television series Matador. Among her last notable film credits was designing the wardrobe for Alfredson's 1982 drama film, The Simple-Minded Murder.
