"Pulp Fiction" star Samuel L. Jackson has challenged his fellow celebrities to participate in an ALS Ice Bucket Challenge-style challenge to show their anger over two controversial police killings in the US.
The 65-year-old wants stars to join him in singing a track called "We Ain't Gonna Stop Till People are Free", inspired by the death of Eric Garner, who was apparently placed in a chokehold by a cop in New York when he was arrested for illegally selling cigarettes, reports contactmusic.com.
The tragedy came just weeks after teenager Michael Brown was shot dead by an officer in Missouri during a scuffle as he was arrested for stealing cigars and after grand juries cleared both officers, thousands of Americans took to the streets to protest against the rulings.
Saturday, the Millions March Nyc in New York attracted an estimated 27,000 activists to the Big Apple, and Jackson has marked the day by launching a social media campaign similar to the ALS Ice Bucket Challenge, which has raised millions for charity.
In a video posted on Facebook, he said: "All you celebrities out there who poured ice water on your head, here's a chance to do something else. I challenge all of you to sing the 'We Ain't Gonna Stop Till People are Free' song."
