Emily Blunt says it was "thrilling" to film the new campaign for Yves Saint Laurent fragrance Opium.
The British actress was announced as the new face of the iconic scent in September.
A behind-the-scenes teaser has been released ahead of the campaign's official debut in December.
The clip shows Emily leaving a party to hunt for the perfume.
"It was thrilling," Emily said in the behind-the-scenes video. "I was given a story to play, and for me as an actress that's very exciting. I'm not just posing or just trying to sell something."
The stunning star was delighted to work with the luxury fashion house. She has loved their work for a long time.
"For me, it's particularly exciting that it's YSL just because I've admired them for many years," she gushed.
"I have great respect for what the fashion house does."
Emily is a firm believer in the power of perfume. The beauty explained that different scents unlock different memories and emotions in people.
"I think really that's what I love most about it - it evokes so much for people. Everyone always says they've smelled something, and remember this beautiful memory they experienced maybe many years ago," she smiled.
"There's something very powerful about it."
However, there were some difficulties during filming. Emily was not used to being so active while wearing sky-scraper YSL heels.
"[I'm] on a mission, which is not that easy to do in really high heels!"she laughed.
"That's what Opium does to you - you suffer through it because you know you need it."
