It's a box office hit, but N.W.A.'s former manager Jerry Heller and CEO of Death Row Records Marion 'Suge' Knight have both come out against how they were portrayed in Straight Outta Compton.
Opening up on the promotional trail for the film on Friday in Sydney, Ice Cube told Daily Mail Australia that he feels both men were depicted accurately, and was particularly unsurprised that Heller felt dissatisfied.
'I don't expect him to start telling the truth now, so I expected him to say that,' Ice Cube, 46, laughed as he sat alongside his son, O'Shea Jackson Jr., 24, who takes on his character in the film.

'We were totally fair with Jerry,' he added.
'I don't have any axe to grind with that guy at all. He was actually a champion for the group when he came to us against outside forces but I just didn't like how he dealt with us internally.
'And that was my problem with it, it was strictly business.
'He's just mad because he ended up in a rap song,' Ice Cube laughed, speaking about his tune No Vaseline that dissed the former manager after he left the group N.W.A. when he felt Heller was not paying him fairly.

The film has also been slammed as 'exaggerated and silly' by the lawyer representing Suge Knight, but Ice Cube is unperturbed by those claims either.
'Is he ever happy?' O'Shea Jackson Jr asked.
'We heard facts and things from people who were there, so we think we are accurate,' Ice Cube said.
Suge Knight is known for his notorious temper and is currently unable to see the film because he is awaiting trial on murder and attempted murder charges after allegedly running over two men on the set of a Straight Outta Compton promotional video.

As he is now: Marion 'Suge' Knight is awaiting trial on a murder charge after an alleged hit and run in a Compton car park, following an argument related to the making of Straight Outta Compton

Movie version: NWA as portrayed in Straight Outts Compton, with Dj Yella played by Neil Brown Jr; MC ren played by Aldis Hodge; Dr. Dre played by Corey Hawkins; Eazy-E, played by Jason Mitchell; and Ice Cube, played by his son O'Shea Jackson Jr.
But Ice Cube is not at all concerned about igniting Knight's anger, saying that he gets on with the 50-year-old.
'I'm not worried, you know, me and Suge always be cool. We always going to be cool,' Ice Cube told Daily Mail Australia.
Attorney Thomas Mesereau, who represents Knight, told The Wrap Universal's N.W.A biopic falsely portrays the fallen hip-hop mogul as a troublemaker who uses violence to get ahead in business.
He said: 'I'm sure he wouldn't like it because a lot of it is exaggerated and silly and ridiculous.

'A lot of the media does not realize how many good things he did for people, particularly in his community…He financed athletic facilities in schools, he gave money to the homeless, money to people in need.'
'He's a good person, and this will come out in due time,' the attorney said.
Heller claims in 'Ruthless: A Memoir' that he was not to blame for the backstabbing which ended the group he called 'The Black Beatles'.
Instead, he pointed the finger at the group's producer Dr Dre and accused him of 'betraying' the group's founder and owner Eazy-E.
Heller claims that Dre set up E to get blackmailed into freeing him from his contract in a deceit that puts to shame the respectable producer he is today who sold his Beats headphones to Apple for 0 million.

'I didn't have that level of understanding of the human animal. I guess that even after three decades I had spent in the rough-and-tumble music business, in a corner of my soul I was naïve,' Heller said.
Heller was a middle-aged white Jewish man who served in the Army and had represented Black Sabbath and Elton John.
Heller hated Cube from the start and writes that 'even in those early days (he) was always difficult'.
He says that Cube 'had a chip on his shoulder' and had an 'adolescent attitude' but admits: 'Sy human beings sometimes make great art'.
Cube was the first to leave the group but it was Dre's departure that brought about the end in 1991.
The R-rated biopic - which cost million to make - about the ground breaking hip-hop group N.W.A. - which stands for Ns With Attitude - performed above industry expectations and took .2million over its debut weekend.
Straight Outta Compton is in cinemas now.
Hero or villain? Dr. Dre - real name Andre Young - is largely positively portrayed in the movie but Jerry Heller, NWA's manager gives a different view, saying that he drove the group apart
