Idris Elba was in attendance when Prince Harry and Duchess Meghan were married on May 19, 2018, but the actor has always remained mum on the details of their wedding reception. However, the actor teased a few more details while appearing on The Tonight Show, starring Jimmy Fallon on Oct. 31.

The Halloween episode featured The Harder They Fall actor dressed to impress in a Halloween costume for a gig later that evening at Annabel’s nightclub in London. Elba was

a well-known DJ called “Big Driis the Londoner” back in the day and performed at Madonna’s wedding. He revealed that the royal wedding reception was the most stressful event he’d ever DJ’d when prompted by Fallon. DJ Big Driis said because of the enormity of the event. He felt the pressure to make sure his friends enjoyed themselves.

“This wasn’t like my cousin’s wedding,” said Elba. “This wasn’t at the community hall — the reception. This was, like a big, big deal. They’re good friends and I wanted to make sure they had a great time, so it was a lot of pressure,” he recalled.

The actor wouldn’t reveal the playlist but in 2019 admitted to playing one song, “I Wanna Dance with Somebody (Who Loves Me)” by Whitney Houston. During the BBC radio interview, he also noted that there may have been some West-coast rap played at the royal reception but would not comment further.

Elba also discussed his collaboration with Paul McCartney for the musician’s new album during the episode.

The actor is currently starring in a new movie with Regina King called The Harder They Fall, based on the true story of Black cowboys in the Old West. The film also features Delroy Lindo, Jonathan Majors, LaKeith Lee Stanfield and Zazie Beetz.

Jay Z was a producer on the film and appeared on the soundtrack with Lauryn Hill, Kid Cudi, CeeLo Green and Koffee.

The Harder They Fall is now in theaters and will stream on Netflix beginning Nov. 3.
