Star-Derailing Role: Maxwell Caulfield blamed this film for killing his budding Hollywood career. After the movie bombed, Paramount dropped his contract. In his own words, "It took me ten years to get over Grease 2." (He did find relative success on the Dynasty spin-off The Colbys only three years after this film.)
Michelle Pfieffer's career nearly suffered this because she was initially considered to be rejected from working on Scarface (1983).
What Could Have Been: Paramount was envisioning up to three more sequels and possibly a TV series. Would Grease 3 have worked with the mid-Sixties and British Invasion music as a backdrop? Would Grease 4 have dealt with hippies? Would there have been a Seventies version, sorta like Dazed and Confused with musical numbers? We'll never know.
