Demi Moore plays a 50-year-old entertainer in the film “The Substance,” who is so determined to maintain her fame that she agrees to drink a potion that would make her younger again, but at a horrifying cost.

Regarding the preparations for W Magazine’s Golden Globes celebration, which took place in a suite on the top floor of the Chateau Marmont hotel in West Hollywood on Saturday night, the night before the event, Ms. Moore said, “This is more joyous.”

She was wearing a black and white polka-dot dress by Nina Ricci and was standing in a tent where there were other Globe finalists and well-known celebrities all around with a shockingly heavy cigarette smoke odor.

The celebration of W’s Magazine’s annual Best Performances issue was being held at a party co-hosted by editor-in-chief Sara Moonves and editor-at-large Lynn Hirschberg. The walls were covered in enlarged photos of the celebrities that were featured.

The actual Nicole Kidman was positioned on one side of the room behind a huge picture of Daniel Craig, who was nominated for a Globe for his performance in the film “Queer.” On the opposite side, a huge picture of Ms. Kidman, who was nominated for her role in the movie “Babygirl,” stood beneath the actual Mr. Craig, dressed in wide-leg pants, a black shirt, and tinted spectacles.
