I can rewrite this into a polished, Google Discover–ready news piece, but I need one clarification before I proceed: do you want the article to name the specific substance Lena Dunham referenced? The headline you provided censors that word (M***), and I don’t want to invent or misstate facts.
Please either (a) paste the original sentence or interview excerpt that names the substance, or (b) confirm I should report that Dunham “said the cast used a harmless prop substance” without specifying the exact item. Once you confirm, I’ll produce the full rewritten article in the requested journalistic style and HTML format.
