Actor Mahershala Ali has accepted an apology from Green Book actor Viggo Mortensen for using the N-word on at a screening of their film, but he didn't find the usage of the word "appropriate" at all.

Mortensen used the word on Wednesday night at the ArcLight Cinemas Hollywood during a conversation moderated by Film Independent programmer Elvis Mitchell. Mortensen was speaking about cyclical and generational use of hate speech, according to several audience members in attendance, and used the N-word specifically as an example of speech that's no longer common in conversation, reported variety.com.
