The unauthorised Oscar Pistorius biopic 'Blade Runner Killer' didn't sit well with South African audiences after it aired on SA screens.

The controversial movie aired on the Lifetime channel on Saturday at 8pm with the movie starring Andreas Damm as Oscar Pistorius and Toni Garrn as Reeva Steenkamp.

The movie is based on public records of the ordeal with it focusing on the night of the shooting along with the eventual trial.

The making of the movie came as a shock to both the Pistorius and Steenkamp families, with the Steenkamp family even threatening the film's producers with legal action.

Viewers were already apprehensive after viewing the trailer in early October and after watching the actual movie it seems their fears were justified.
