Strindberg appeared as Anita Edberg in two Swedish films in the late 1950s. She started her career in "gialli" with Lucio Fulci's A Lizard in a Woman's Skin in 1971 and starred in her first lead role that same year, in Sergio Martino-directed The Case of the Scorpion's Tail. In 1972, she starred in two more gialli; in Aldo Lado's Who Saw Her Die? and Martino's Your Vice Is a Locked Room and Only I Have the Key.
After the early 1970s, Strindberg acted in many types of "genre films"; a women in prison film Women in Cell Block 7, the Exorcist-like horror film L'anticristo (The Antichrist) and the poliziotteschi film Milano odia: la polizia non può sparare (Almost Human), directed by Umberto Lenzi. Her last film was Riccardo Freda's Murder Obsession (Follia Omicida), also known as Fear co-starring Laura Gemser.
