Samuel L. Jackson wrote an NSWF gospel for Hitman's Bodyguard,

It seems like Samuel L. Jackson has turned into a master lyricist for 'Hitman's Bodyguard'

On Friday, Jackson debuted 'Nobody Gets Out Alive,' a song he wrote and performed for the film's soundtrack.

Talking about the song, composer Atli Orvarsson, said, "He and Ryan Reynolds were sitting, just the two of them, in his car talking, and he just kind of breaks out into song. I think it was more or less improvised on the set," according to The Hollywood Reporter.

Director Patrick Hughes recognised Jackson was on to something, and encouraged him to keep working on it, soon sending the idea to his composer to help arrange.

Thus began an international collaboration, with Orvarsson and Jackson sending ideas back and forth, as the composer travelled the world recording different segments in places like London and New York.

The composer added, "It was an international collage. re is a gospel element too. At the end of the day, Samuel Jackson's character is a hitman, but his history, you learn in the film, is very complicated and there's kind of a gospel aspect to his character and his story."

Helmed by Patrick Hughes, the film also stars Ryan Reynolds in a pivotal role.

The flick is slated for an August 18 release.
