Rocky and Flash Gordon are among classic movies to have ดาวน์โหลด slotxo had their ratings tightened by the British Board of Film Classification (BBFC).
The move from Parental Guidance (PG) to 12A is "as a result of changing standards in society," the body said.
Flash Gordon's "moderate violence, language, sex references and discriminatory stereotypes" were cited, along with domestic abuse in Rocky.
The BBFC reviews its classifications every four to five years.
BBFC chief executive David Austin said in the body's annual report: "We talk to over 10,000 people every four-five years... to ensure our policies remain in step with parental expectations and societal standards on an ongoing basis.
"As a result of changing standards in society, it's not infrequent that a distributor will submit something to us that we have classified in the past, but which we need to take a fresh look at under our current guidelines."
The PG rating says a film should not unsettle a child aged around eight or older while 12A recommends children under 12 shouldn't watch without being accompanied by an adult.
Of the 93 complaints the board received last year, 27 were about 1980 space opera film Flash Gordon.
The movie's 40th anniversary re-release was reclassified up to 12A partly due to the inclusion of "discriminatory stereotypes".
The BBFC did not say what the stereotypes were. However Flash Gordon's main villain, Ming the Merciless, was of East Asian appearance but played by Swedish-French actor Max von Sydow.
