Bosses at GMH Productions have secured the rights to Done It All, a script named after Haggard's hit song, which details his early days in a life of poverty and crime to his subsequent rise to fame.

The project originally started with producer Donald Kushner and Carl Cooper, friends of Haggard who put the two in charge of making his life into a movie.

Kushner then recruited Cinderella Man scribe Cliff Hollingsworth to write the spec for Done It All, according to Deadline.

Haggard passed away at his home in Northern California on his 79th birthday last week (ends08Apr16), due to complications from pneumonia.
