Sky Cinema has added warnings about "outdated attitudes and language" to films including Gone With The Wind, Flash Gordon, The Goonies, and the original Dumbo.
The TV network says that 16 films currently being screeend on their service may feature "cultural depictions which may cause offence today".
The move comes in light of on-going civil rights protests in the US, which have spread across the globe following the death of George Floyd while in police custody.
"Sky is committed to supporting anti-racism and improving diversity and inclusion both on and off screen," a Sky spokesperson said.
"We constantly review all content on Sky's owned channels and will take action where necessary including adding additional information for our customer to allow them to make an informed decision when deciding what films and TV shows to watch."
In recent weeks, a number of TV shows and films have been taken down from streaming services because of racist attitudes or stereotypes.
Gone With the Wind, the classic 1939 film about the American Civil War, was removed from HBO Max for its "racist depictions" and "racial prejudices", but was later restored to the service.
Shows including Little Britain and The Mighty Boosh have also been removed for the use of Blackface.
An episode of Fawlty Towers was initially removed from UKTV for its use of racial slurs, but was later reinstated with a warning about "potentially offensive content and language". Star John Cleese criticised the initial decision to remove 'The Germans’ spisode of the classic sitcom, calling it "stupid".
