MacDowell sported a brown-and-tan Christian Dior dress, which was sleeveless with a striped pattern and V-shaped neckline. Mirren chose a more striking look: a long-sleeved gown decorated with silver sequins and metallic fringe.
But it was their red-carpet interactions that really stole the show. Not only did MacDowell and Mirren pose for photos together, but they also embraced in passionate hugs before the "Mother and Son (Un Petit Frère)" screening.
They then danced together, with MacDowell twirling Mirren across the red carpet.
Though their outfits didn't match on either occasion, their stunning silver hair did.
MacDowell previously described her gray strands, which she debuted at last year's Cannes festival, to InStyle as a "really important" style moment that helped her accept her "authentic, true self."
Mirren, on the other hand, told Vogue in 2021 that going gray was "easy" for her because she's always had light-blonde hair.

"Going gray is to be encouraged — that's not to say you can't have fun with your hair, because it's a very important part of how you feel about yourself," she said at the time. "People should do whatever makes them feel comfortable."
