In the trailer the words "heart of a champion, mind of a killer" flash up on screen.Pistorius' family has also slammed the TV movie.

NPA spokesman Luvuyo Mfaku said: "We stipulate clearly that the sentence imposed is shockingly low.

"The presiding officer has the discretion to deviate from the minimum prescribed sentence when compelling and substantial circumstances exist. with this matter, the presiding officer exercised that discretion in a very lenient manner".

His brother Carl released a statement in which he said the Pistorius family distances themselves from the Hollywood film and sources say they have retained a top barrister to take action.

Carl said: "The film was made with blatant disregard of both the Steenkamp and Pistorius families, as well as complete disregard for Reeva and Oscar.

Reading out the court’s decision, the judge said: "The sentence imposed...

in respect of murder is set aside and substituted with the following: the respondent is sentenced to imprisonment for a period of 13 years and five months.” Pistorius killed Steenkamp in the pre-dawn hours of Valentine's Day 2013 after shooting four times through a closed toilet cubicle door in his home.

The court itself should revisit certain things in sentencing. Judge Masipa has the power to reduce South Africa’s minimum 15-year prison term for murder after listening to evidence from the prosecution and defence.

“We think it’s time that people should see what those bullets did; what the accused did.” Defence lawyer Mr Roux had suggested the application to release the images was inappropriate at this stage of the proceedings. She will announce Pistorius' sentence for the murder of Ms Steenkamp on 6 July.

The pictures showing Ms Steenkamp's fatal wounds, including a severe head injury, had previously been withheld from the public in order to “protect the integrity of the deceased”.

However, her father, Barry Steenkamp, asked for the pictures to be released to the public on Tuesday when he broke down in the witness box to tell the court how he and his wife have struggled to cope since his daughter’s murder.

His lawyers have just one avenue open to them if they want to challenge the new sentence handed down by the Supreme Court, and that is to appeal to the Constitutional Court, the highest court in South Africa.
