It's a comedy caper from 1959 – and considered a Hollywood classic.
But Some Like It Hot, featuring three of the biggest stars from the era – Marilyn Monroe, Tony Curtis and Jack Lemmon – appears to have fallen foul of the increasingly po-faced British Board of Film Classification.
It has decided the much-loved movie needs a stricter rating – pointing to the fact that it features car chases, innuendo and flirting.
Some Like It Hot, nominated for six , has been reclassified as a PG for future home entertainment releases – having last been classified as a U in 2007.
The step will be seen by critics as an example of the board reflecting fashionable attitudes.
The U stands for 'universal', meaning suitable for all audiences, while PG warns that parental guidance is advised.
The Billy Wilder film, about two musicians who dress as women to flee mobsters, has also been slapped with extra content warnings.
One of these is the category 'threat and horror,' under which it warns of a 'car chase sequence resulting in crashes'.

It also warns of characters being 'threatened with guns' but adds: 'These situations are often presented with comic elements.'
Under the category 'sex', it says there is innuendo regarding sex and women's physiques. Characters are also shown kissing, and there are scenes of flirting.'
Last year the BBFC upped the age limit for the home release of West Side Story to 12 from PG.
