Chevy Chase, star of the NBC comedy, "Community," has apologized for an obscenity-laced rant Friday, in which he used a racial slur.

The frequently outspoken actor, who marched in the civil rights movement, was said to be frustrated with the increasingly bigoted language written for his character, Pierce Hawthorne.

Sources close to the show, according to Deadline Hollywood, said the 69-year-old comedian  snapped and predicted that next he would have to call the show's two black characters, Donald Glover and Yvette Nicole Brown, the N-word. Chase has said his outburst was not directed at them, and "apologized immediately" according to the Hollywood Reporter.

Chase's most recent tirade isn't his first widely publicized spat on the “Community” set. Earlier this year, in a voicemail leaked to TMZ, Chase called the show's creator, Dan Harmon, a number of profanities and insulted his writing abilities after Harmon reportedly led the cast into a chant of “F—k you, Chevy Chase,” while Chase’s wife and daughter were present. Harmon was later dismissed from the show, which has been struggling recently in the ratings.

Chase is known to be unhappy with his role on the show, and recently called his decision to join the cast “a mistake,” in a February interview with the Huffington Post.

“It was a big mistake! I just sort of hung around because I have three daughters and a wife, and I figured out I might as well make some bread, every week, so I can take care of them in the way they want,” Chase said in the interview. “The hours are hideous, and it’s still a sitcom on television, which is probably the lowest form of television.”

Chase was careful to praise his cast mates, however, adding that working alongside them is what he enjoys most about the show. “I think the reason I have stuck around is because I love these kids, the cast -- they are very good.”

"Community" was originally set to premiere last Friday, Oct. 19, but NBC has since rescheduled its premiere for an undetermined date.
