Jonah Hill wrote a personal letter to Morrissey to convince him to write a song for his directorial debut.
The 34-year-old actor helmed the new comedy-drama 'Mid90s', and Jonah has revealed how he convinced one of his musical heroes to contribute to the project.
He shared: "We didn't have money and the soundtrack is crazy. We had no money, so I had to write letters to all of my favourite artists ... Every song that's in the film, I wrote the scene to have that song in it."
Morrissey, 59, wrote one song for the soundtrack and Jonah is thrilled that he agreed to contribute to the movie.
The Hollywood star joked that he and the controversial musician are now "best friends".
Jonah told 'The Tonight Show Starring Jimmy Fallon': "I wrote to Morrissey, and I wrote him a really personal letter, and he emailed back, 'It is my pleasure and I can't wait to see Mid90s, Morrissey.' All caps...
"I was like, Morrissey knows what 'Mid90s' is! He said the words 'Mid90s'! Morrissey is my best friend! We are best friends! I'm best friends with Morrissey!"
Meanwhile, Morrissey previously bemoaned the state of the music industry, describing it as "obvious and predictable".
He explained: "There are no bands or singers who become successful without overwhelming marketing. There are no surprise success stories.
"Everything is stringently controlled, obvious and predictable and has exactly the same content.
"So, we are now in the era of marketed pop stars, which means that the labels fully control the charts, and consequently the public has lost interest. It's very rare that a record label does something for the good of music."
