 CONT: At the end of _Rocky IV (1985)_ (qv), Rockys son is under the  age of 10. However, at the beginning of Rocky V, which in the  movies timeline takes place only a week after the end of Rocky IV,  the boy is already 12 or 13. In addition, Rocky IV is set in 1985  (judging from the license plates), yet in this movie, Rocky Jr. and  his friends are watching the 1989 movie  _Christmas Vacation (1989)_ (qv).
