Summary:

• **What is AI-Generated Video?** Artificial intelligence (AI) is computer technology that can create fake videos of real people doing things they never actually did. In this case, someone used AI to make a video showing actors Tom Cruise and Brad Pitt fighting each other, even though they never really fought.

• **Why Are People Upset?** Hollywood actors and other people are concerned because this technology can be used to create false videos that trick people into believing things that aren't real. This raises important questions about whether it's fair to use someone's face and image without their permission to make fake videos.
