Back to the Future to See Before You Die". "Back to the Future" success led to two film sequels: "Back to the Future Part II" and "Back to the Future Part III". "Part II" was released on November 22, 1989, to mixed reviews and similar financial success as the original, finishing as the third highest-grossing film of the year worldwide.
