Michael director Antoine Fuqua mistook a picture of Jafaar Jackson for an old photo of Michael Jackson.
The 60-year-old filmmaker has recalled how he was "blown away" when Director of Photography Bob Richardson showed him a picture of the 26-year-old star before he had signed up to work on the biopic of the late King of Pop - who died in 2009 aged 50 - and it helped convince him to sign on.
