Adrien Brody loves the "storytelling" in brooches.
The Brutalist actor can often be found wearing a decorative pin when he dresses up on the red carpet, because not only does he think they add an "interesting" touch to a "conservative" outfit, but he also likes the stories behind the designs.
He told Interview magazine: "I find them really beautiful. I think as a man to a formal event, you’re often wearing something black tie that’s relatively conservative, and it’s a very interesting accoutrement to embellish that.
"There’s artistry and layering in the storytelling of the brooches that are all really interesting.
"The last one that I just wore at the Met Gala is based on Swan Lake and Princess Odessa, I believe. The Princess is looking into her reflection in the lake and that kind of solitary, longing, lonely moment."
The 53-year-old actor noted brooches have grown far more popular among Hollywood men since he first started wearing them on his suits some time ago.
He said: "It’s funny because when I started wearing it, far fewer men were wearing brooches.
"Now I notice that when I show up to an event that quite a few people are wearing one. But before it was not a very common form of men’s jewellery."
Elsewhere in the interview, Adrien revealed he had spent almost six months living alone in a hotel room.
The Oscar-winning actor made his Broadway debut last month in The Fear of 13, which is based on the true story of Nick Yarris, who spent 22 years on death row for a murder he didn't commit, and in order to get into character he spent five months isolating himself away from his loved ones and minimising social interactions.
Adrien - who first starred in the show in London before it transferred to New York -said: “It is lonesome, of course.
“But I'm playing a man who has lived far deeper in that isolation. What I experience is only scratching the surface.”
The Pianist star admitted the experience has been "solitary", but he felt it was essential to accurately show Nick's experience.
He said: "It doesn't just come from the responsibility of these four or five months, it comes from the life I've lived up to this point, from accessing those experiences and honoring the people reflected in Nick's story and journey.
"Living alone in a room for nearly half a year, most days of the week, is part of what I give to the work.
"It's a strange thing. There is a need to sacrifice certain comforts and freedoms for roles like this. It's not the first time I've done it, and it won't be the last.
" I think that sacrifice leads not only to better work but to a greater appreciation of life, to devoting as much of myself as I can for a finite period, and then letting it go and trying to live more joyfully."
