But viewers have mocked the clip, saying it's obvious the actors were reading from a script - and have slammed them for making the Black Lives Matter movement about themselves.
"No matter how well-intentioned, they always fall back on performative nonsense. They have this insatiable need to come out 'good' and righteous in every situation," wrote one person on Twitter.
"How do celebs keep messing this up so badly? Stop making this about yourself and donate $1 million each to a local organization helping Black people!!!!!" wrote another.
"Ending Racism: The Musical," joked another.
The video has also been compared to Gal Gadot's star-studded "Imagine" montage she released during the coronavirus outbreak, which also sparked outrage.
