The clip shows some men arguing on a street in New York over a painting.
At one point, a man with a blue cap shows up and elegantly ends the scuffle between the two men who had already gotten somewhat violent.
The video was shot by onlookers. When the man resembling Gosling appears, girls can be heard screaming with excitement.
One of them exclaims: “That’s the guy from the movies!” one exclaims.
The actor’s rep hasn’t yet commented.
