The Netflix streaming service has admitted to using artifical intelligence for the first time in order to scale up the look of a foreign sci-fi series.

Netflix said AI was used to produce visual effects that appeared for the first time on screen in one of its original series, employing a technology that has been a source of anxiety throughout Hollywood.

Speaking at the company’s post-results conference call, the company’s co-CEO, Ted Sarandos, said that the platform had “the very first GenAI final footage to appear on screen” in an Argentine show called “El Atonata.” He noted that Netflix’s internal production group teamed up with producers to use AI to create a scene of a building collapsing.
