Turner accused her Peggy Sue Got Married co-star of drink-driving and theft in her autobiography Send Yourself Roses.
She also alleged that Cage deliberately disobeyed his director uncle Francis Ford Coppola on the set of the 1986 movie.
Cage began libel proceedings against Turner at London's High Court last February, insisting the memoir was full of false claims about him.
He subsequently won the case, and Romancing The Stone star Turner was forced to apologise - but the veteran actress now considers Cage a friend.
Turner tells CYInterview.com, “I certainly consider him a friend, and I believe he feels the same”, adding that the suit “really was more in terms of a legal system than me.”
