The British director of a new film that depicts the life of OJ Simpson claims his feature will shed new light on the murder of the sport star’s ex-wife, Nicole Brown.

Joshua Newton spent 18 months immersing himself in court documents to craft his story of the murder of Nicole in 1994 before embarking on his film, Nicole & OJ.

And the filmmaker believes he has uncovered a giant conspiracy that saw the odds stacked against former American Football star O.J. and meant the true killer of Nicole (who was stabbed to death in her own home aged 35) got away.

OJ was initially tried for the murder of Nicole and her friend Ron Goldman but was ultimately found not guilty following the completion of the trial in 1995.

O.J. was later found guilty of wrongful death and battery of Ron Goldman in a wrongful death civil trial - however, he was not sentenced to jail but was ordered to pay over $33million (£25million).

OJ was later jailed in 2008 for his part in a Las Vegas robbery.

Speaking to the Daily Mail about his film surrounding the murders of Nicole and Ron, Joshua claims he has uncovered evidence that conclusively proves OJ was innocent and that he was the victim of a conspiracy.

"Nicole & OJ will reveal the untold circumstances leading up to the murders and why and how Nicole and Ron were killed and the cover up that followed," he says.

Following his research, Joshua claims that evidence was wrongly presented in order to paint OJ in a bad light - and in particular, he highlights that prosecution during OJ's case had said he showed no emotion when he was told his wife had been killed.

"The reality is that O.J. exploded into rage because of his grief, repeatedly asking, 'what do you mean Nicole is dead?' while the detective on the phone kept telling him he has no information," Joshua claims.

"This is just one example of many where the prosecution attempted to deceive the jury, the press and the public. Thankfully the jury saw right through it and that's why OJ was acquitted."

Joshua says public interest in the case compelled him to make the film.

"The media was assisted by prosecutors drawing on unethical means to persuade the public of his guilt because they knew their evidence would fail to persuade the jury," he said.

And he went on to suggest he thinks OJ is innocent and was the victim of a witch hunt.

"It's very worrying. OJ was fortunate that he could afford a brilliant defence team to challenge a prosecutorial system more concerned with winning than with justice. But what about countless defendants who are innocent and don't have any money? Justice for them isn't an acquittal, it's a life sentence or even death," he added.
