Performing in Yugoslav films from 1949, she developed an international career in the 1950s, appearing in the 1960s in such British television series like Danger Man, Maigret, The Benny Hill Show and The Saint.
Regin was born as Nadežda Poderegin (Serbian Cyrillic: Надежда Подерегин) on 2 December 1931 in Niš, Serbia, Kingdom of Yugoslavia.
He was executed by the German occupation forces during World War II during the Kraljevo massacre in October 1941.
[5][6][7] After the Soviet Red Army arrived in Yugoslavia and participated with the Yugoslav Partisans in forcing out the Germans, a 13-years old Regin shortly acted as an interpreter in the Kraljevo hospital, as she learned Russian from her father.
She graduated 20 May 1954 in the role of Anka, from the play Lovers by the unknown 16th century author, performing in the Belgrade Drama Theatre.
From the 1954 production of The House on the Coast, directed by Boško Kosanović, she shortened her surname from Poderegin to Regin.
[6] Other German-language films include Roman eines Frauenarztes (1954; by Falk Harnack), Du mein stilles Tal [de] (1955; by Leonard Steckel) and Goodbye, Franziska (1957; by Wolfgang Liebeneiner).
[6] Still, she soon acted in British projects like the series The Adventures of William Tell, which was her television debut, and The Invisible Man,and the feature film, Don't Panic Chaps!.
The movie tells a story of British and German soldiers stranded on an island, who decide to peacefully co-exist because they can't leave.
However, one day a girl, played by Regin, arrives on the island and the soldiers resume fighting, this time because of her.
[6] She appeared in many British TV series in this period: International Detective, Danger Man (where she played a Christine Keeler-sque character), Maigret, Richard the Lionheart, The Benny Hill Show, Crane, The Saint and Comedy Playhouse.
And when we were filming scenes from the From Russia With Love, from the James Bond franchise, he [Armendariz] was severely ill, actually, he was dying.
Director Terence Young was aware of what is happening to Armendariz so he decided to film all his scenes, including those with me, in only one day.
[5] Of successor Bond Girls, she especially praised Bérénice Marlohe from Skyfall, and generally described it as a "very powerful film", despite being nostalgic for the older entries in the franchise.
She also wrote a children's story, The Puppet Planet, and in the years prior to her death, she worked on her memoirs, titled Recollections.
[5] In Cannes, Regin met Michael Szrajber (1922–2009), a Polish-born British World War II parachute airman turned industrialist.
