Harbour, 47, shot to stardom starring as Jim Hopper in Netflix’s hit series Stranger Things.
Before this, he had supporting roles in blockbusters such as Brokeback Mountain (2005) and the Bond film Quantum of Solace (2008).
More recently, Harbour discussed a variety of topics while promoting his new Christmas film, Violent Night, on Jimmy Kimmel Live!
But one tale about working for the ‘Like a Virgin’ singer, 64, really shocked viewers.
Watch David Harbour recall the ‘creepy’ audition below…
He described his audition for Madonna’s W.E. as ‘crazy’ and a ‘real cloak-and-dagger’ type experience.
Harbour explained: “I got a call from a casting director that I knew very well saying they’re putting together a top-secret movie read-through, but you just have to show up at the St Regis and go in this room, and all will be revealed.
“And I was like, this is really weird and creepy.”
When Harbour questioned why he had been selected for the audition, the casting director declined to give much away.

All he was told was that the director – whose identity he didn’t know at the time – had seen him in 2008’s Revolutionary Road: “You have a s** scene in it, and they thought you were s**y.”
Harbour went on: “And so all weekend, I was literally thinking about Ridley Scott and Martin Scorcese.
“I show up at the St Regis and I get in the room, and there’s a bunch of other New York actors there, and in walks Madonna, who’s directing this movie.
“The first thing that flooded over me, I was like, ‘Wow, Madonna thinks I’m sexy’.”
The Black Widow star said the audition was a ‘truly harrowing, exciting experience’, as he had had a crush on the ‘Vogue’ hitmaker since seeing her ‘Open Your Heart’ music video in 1986, aged 11.
He added: “So there I am, in this boardroom of the St Regis, and it all comes flooding back.”
Along with Harbour, the film also starred Abbie Cornish, Andrea Riseborough and James D’Arcy.
However, the film was not a success, with Harbour admitting that W.E. was ‘not a terrific movie’ – which is backed up by its 12 per cent score on Rotten Tomatoes.
He did say, though, that the experience led to him attending a birthday party of Madonna’s, which he described as ‘one of the coolest things I’ve ever done’.
He said: “She came in, and she was in like this gorgeous, emerald dress.
“And then the party started, and she put on sweatpants, and they just cranked Madonna music.
“I danced with Madonna to Madonna music. On my headstone, that is it!”
