A pair of protestors from Just Stop Oil disrupted a performance of The Tempest, starring Sigourney Weaver on London's West End.
The duo got up on stage as Weaver was performing - and unfurled a banner and delivered a speech before they were bundled off by authorities.
Weaver was also escorted off stage by a member of the theatre's staff.
UK correspondent Enda Brady says the activists were met with booing - and also a few cheers.
