The movie has inspired protests in Malta, London and Italy, as well as Los Angeles.
It’s the film up for an Oscar this weekend whose quirky activism has inspired copies in Europe and the US.
“Three Billboards Outside Ebbing, Missouri” — which has been nominated in the Best Picture category — tells the story of an aggrieved mother who uses red-and-black roadside billboards to shame local police.
It has sparked similar-style billboards across the world.
Hollywood woke up to a trio of hoardings in Los Angeles on Wednesday, which referenced the industry’s sexual misconduct accusations.
In Europe, there have been copycat stunts in Malta, England and Italy.
Protesters in Valletta used the billboard’s black and red design to call for justice over the murder of investigative journalist Daphne Caruana Galizia.
In Naples, activists used them to allege that the Northern League is now trying to woo southern Italian voters having previously said they stink.
The three billboards read together: “I said you stink. Now I want your vote. Why not, Southerners?”
In London they were used to protest about the perceived lack of justice around the Grenfell Tower fire tragedy, which left 71 people dead.
