Will Smith has spoken about his decision to direct an episode of his sitcom All Of Us.

The episode features an African-American character questioning the meaning of the 'N word', and Smith agreed to get involved because he felt that the subject matter should be handled delicately.

"The revisionist perspective on the word is that we have taken the word and we have transformed it and we have turned it into a word, much like the gay community did with the word 'queer.'" he told WENN.

"We flipped it and threw it in the face of the oppressor, but there's also those who would prefer that the word go the way of most words - it just dies and goes away. The show doesn't follow one side of the other - it's very interesting."
