Ha ha ha. Why should she recognize him? Baz Luhrmann is quite famous, but he's not a famous face, and even when someone has a famous face, would you recognize that face if it turned up randomly on the street? You wouldn't know if you didn't. And how many times have you had to say, "Was that [name of celebrity]?" Ever been in the middle of a conversation with someone and had the sneaking suspicion that he thinks you're supposed to know he's somebody? Like Luhrmann in that video, most celebrities, I believe, would refrain from saying the dreaded words "Don't you know who I am?"
Anyway, it's a hilarious conversation. Luhrmann says something about marriage that the TikTokker, Georgia Godworth, paraphrases as “It’s a loose contract where you can fuck other people occasionally.” Luhrmann continues the conversation thoughtfully and politely. Watch the whole thing.
