Production on Chappelle's Show has mysteriously come to a screeching halt, and now a premiere date for the third season of Dave Chappelle's Comedy Central hit is completely up in the air. "All parties are optimistic that production will resume in the near future," reads a statement from the cabler. Paramount is also expected to push back the release of Chappelle's Season 2 DVD (originally scheduled to come out at the end of May). Since the star just signed a $50 million deal for two years, we're guessing this is not a money issue.
