Hollywood actress Scarlett Johansson has taken legal action against an AI app developer for using her name and likeness in an online advert without her consent. 

AI image editor Lisa AI started with an old clip of Johansson behind the scenes of Marvel’s 'Black Widow,' before featuring an AI-generated version of Johansson’s voice stating, 'It’s not limited to avatars only. You can also create images with texts and even your AI videos. I think you shouldn’t miss it'. 

A disclaimer under the advert said, 'Images produced by Lisa AI. It has nothing to do with this person.' 

However, Johansson's voice and likeness had been used without permission, prompting the actress to take legal action against Lisa AI and its developer Convert Yazılım Limited Şirketi.

The fracas prompted commentators and lawyers to highlight the lack of consensus on AI and deepfake legislation in the USA and elsewhere and to point out the need for strong legal frameworks that would offer individuals strong protection from unauthorised AI-generated content.
