According to producer Expectation, the film will be a "moving and inspirational account" of the last chapter of Ozzy's life.
It was filmed over three years and has been told through "unique and intimate access" to the whole family, including Ozzy, wife Sharon, son Jack and daughter Kelly.
The documentary will feature what makers described as the "extraordinary rollercoaster" of the Osbournes' lives as Sharon and Ozzy tried to realise a long-held dream to move back to the UK.
It was originally announced as a series, Home to Roost, in 2022, but the project evolved as Ozzy's health continued to deteriorate.
