""How do you do?" from Sweden, we have this blond vision, Karen Verne, definitely a Hollywood prospect." (Film Fun, 1941)
I couldn't find anything about a Karen Verne from Sweden. The only actress I found named Karen Verne, was born in Berlin, Germany and married to Peter Lorre at one point in time. Many sources say that Karen's German heritage was disguised because of her debut during World War II. Perhaps they said she was from Sweden.
