Dame Helen Mirren yelled at a group of street drummers to be quiet while still dressed in her stage costume as Queen Elizabeth II.
The incident took place in London's West End on Saturday after a parade promoting a gay and transgender festival paused on Rupert Street and the drummers continued to play.
Dame Helen, performing in The Audience at the nearby Gielgud Theatre, eventually emerged in full costume.
BBC London's Sarah Harris spoke to comedian Chris Dangerfield, who filmed the altercation, and a number of theatre-goers.
