Who got her first big break in the movie "Grease 2"?

"Grease 2" is a 1982 American musical romantic comedy film and the sequel to "Grease", which is based upon the musical of the same name by Jim Jacobs and Warren Casey. The film was produced by Allan Carr and Robert Stigwood, and directed and choreographed by Patricia Birch, who also choreographed the first film and the Broadway musical. It takes place two years after the original film at Rydell High School, set in the 1961-1962 school year, with an almost entirely new cast, led by actors Maxwell Caulfield and Michelle Pfeiffer.

Michelle Pfeiffer played the part of Stephanie Zinone, the leader of the Pink Ladies. With only a few television roles and small film appearances, the 23-year-old Pfeiffer was an unknown actress when she attended the casting call audition for the role of Stephanie. Other better-known actresses up for the part included Lisa Hartman, Kristy McNichol, Andrea McArdle, and singer Pat Benatar. Pfeiffer was a wild card choice, but according to Birch, she won the part because she "has a quirky quality you don't expect."
