'Deepfake' Queen delivers alternative Christmas speech in warning about misinformation

London (CNN)A fake Queen Elizabeth danced across TV screens on Christmas as part of a "deepfake" speech aired by a British broadcaster. The real British monarch traditionally delivers a Christmas Day speech aired around the world. But her speech on Friday at 3 p.m. was followed by a digitally-created fake of the Queen, aired on Channel 4 and voiced by an actor, warning viewers to question "whether what we see and hear is always what it seems." Channel 4 said the video was created as a "stark warning" about technology and the proliferation of fake news. The broadcaster said the video was supposed to offer "a stark warning about the advanced technology that is enabling the proliferation of misinformation and fake news in a digital age."
