Comedy superstar Dave Chappelle is coming to the Johnny Mercer Theatre on Dec. 20.

At age 40, Chappelle is a comedian, actor, screenwriter and television and film producer. While his comedy has been wildly successful, his career also has been marked by controversy.

Despite being booed offstage at the Apollo Theater's Amateur Night as a budding comic, Chappelle persevered and became part of the New York comedy circuit. He made his film debut as "Ahchoo" in Mel Brooks' "Robin Hood: Men in Tights" in 1993, but turned down the plum role of "Bubba" in "Forrest Gump."

Chappelle has appeared in films such as "The Nutty Professor," "Con Air," "Blue Streak" and "Undercover Brother." He co-wrote his own part for 1998's "Half Baked," which was commercially successful and has become a cult hit.

In 2000, Chappelle did an HBO special, "Dave Chappelle: Killin' Them Softly," In 2004, he had a special on Showtime, "Dave Chappelle: For What It's Worth."

In 2003, his sketch comedy television series, "Chappelle's Show," debuted. It was a huge success for two years, but Chappelle abruptly quit during the filming of the third season, stunning fans and TV execs alike.

The show's first-season DVD became the best-selling TV series of all time, even beating out "The Simpsons," "Family Guy" and "Friends." The show continues to run in late-night syndication.

While Chappelle has continued to tour and perform stand-up, his shows have at times been disrupted. In a June 2004 stand-up performance in Sacramento, Calif., he walked off the stage after berating his audience for constantly shouting a catchphrase from his popular Rick James sketch from his television show.

In August 2007, Chappelle made an appearance in Savannah. Although the show sold out, it was marred by hecklers and random screaming.

This past August, Chappelle returned to stand-up with the Oddball Comedy & Curiosity Festival. In Hartford, Conn., he walked off the stage because of hecklers, but so far, no other incidents have been reported.
