In the United States, she is most widely known for having doubled for Jennifer Beals in the 1983 movie Flashdance. At the time of the film's release, Jahan's role was controversial for several reasons. Beals was an unknown Actress when Flashdance premiered, and throughout the movie were close-ups of what was purported to be Beals' body. However Marine Jahan's contribution was not listed on the movie's opening or ending credits, and because the movie was a huge hit by the time the truth of Jahan's participation had become public knowledge, some felt deceived to learn they had been looking at Jahan's dancing (and bicycle riding), not Beals'. The producers of the film stated they had made no secret of having used a stunt double, and Jahan's name did not appear because Paramount Pictures shortened the closing credits.
