Rocky V is the last and probably least known of the Rocky sequels.
Released on December of 1990, Rocky V stars Sylvester Stallone, Talia Shire, Stallone's real life son Sage Stallone and real life boxer Tommy Morrison (who, in 1993 beat George Foreman for the vacant WBO world Heavyweight championship) as boxer Tommy Gunn, an ingrate character who only uses Rocky for his connections and to try to win the world Heavyweight title. Sage Stallone played Rocky Jr, whose attempt to learn how to box also turned out to be an attempt to try to get his father's attention.
According to the movie's producers, the fifth installment in the Rocky series was an attempt to accuse several real life boxing people without pointing out fingers at anyone directly.
