Apa will be starring the film as the boyfriend of star Amandla Stenberg, Variety reported.
Fox has ordered over a week of re-shoots in Atlanta to add Apa to the film. "The Hate U Give," based on the Angela Thomas' novel of the same name, explores race and police brutality.
Lawley, a YouTube star, was fired in February after a video surfaced of the actor using racial slurs.
"I respect Fox's decision to recast this role for 'The Hate U Give' as it is an important story, and it would not be appropriate for me to be involved considering the actions of my past. I understand the impact and I have grown and learned since then. From now on I plan to use my voice for positive change," he said at the time.
