Jennifer Lawrence's version of 'The Hanging Tree' has been uploaded to YouTube.
Featuring in Mockingjay - Part 1, Lawrence's rendition of the song takes lyrics from Suzanne Collins's novel.
The melody was created by 'Ho Hey' hitmakers The Lumineers.
In the film, Katniss Everdeen (Lawrence) sings 'The Hanging Tree', a song she learned from her father when he was alive.
Director Francis Lawrence revealed that the actress was "horrified" about having to sing in Mockingjay, but said her performance was "great".
Mockingjay - Part 1 is out now, while Part 2 is due for release on November 20, 2015.
