Ice Cube Won't Settle for a John Witherspoon CGI in 'Last Friday'

Ice Cube's gone back to the drawing board with the fourth installment of "Friday" ... and he's clearly pissed.

The N.W.A. rapper revealed there's been some major beef between him and the film's production studio New Line Cinema ... for dragging its feet on green-lighting "Last Friday." The rub and possible deal-breaker ... John Witherspoon -- who plays Mr. Jones, Ice Cube's father in the film -- has died.

So, when we got Cube Friday at LAX, we asked if he'd ever considered using CGI in the film -- since Carrie Fisher's fam was okay with a Princess Leia CGI in "Star Wars: The Rise of Skywalker" -- and he could not have been clearer.

"Last Friday" is the fourth and final installment of the 'Friday' franchise that kicked off in 1995. It's been about 18 years since the last 'Friday' film, and Cube says, "It's all on New Line, man." He's especially pissed cause, if New Line Cinema didn't take its sweet time, they easily would've been able to put Witherspoon in the flick.

Back in May, Cube revealed he wanted to release the film on April 26, 2020 ... but that's clearly not happening now ... if ever.
