Joining TikTok has become something of a trend for Hollywood celebrities stuck at home like everyone else. So it wasn't necessarily surprising to see Tom Cruise on the app, sharing videos of himself playing golf and pratfalling around the house. But the strange thing is that Cruise never actually made the videos. And the account that posted them, DeepTomCruise, wore that on its sleeve: it was openly the work of a talented creator of "deepfakes", AI-generated video clips that use a variety of techniques to create situations that have never happened in the real world. Despite being open about its falseness, the account's videos are so realistic that they still prompted wild speculation.
