Entertainment Weekly, September 12, 2011:

South Park creators Trey Parker and Matt Stone have confirmed to EW that they plan to adapt their Broadway hit The Book of Mormon for the big screen. "Hopefully it will have a big run and a big tour and then we can do the movie in several years," says Parker, who penned the musical with Stone and Avenue Q co-writer Robert Lopez.

Hollywood Reporter, September 20, 2011:

Countering recent press reports that suggested a movie version of the Broadway show is in the planning stages, Parker says there's no movie in the works at the moment, [..]

Parker explained that the whole idea of an immanent movie came about when a reporter asked the duo if they would ever consider a feature film version of their hit musical. Said Parker with a laugh, "We said, 'Yeah, I think we could do a Book of Mormon movie,' and they were like, "Book of Mormon Movie! It's coming!'"

The sad thing is that this kind of behavior isn't limited to the Hollywood press. Our entire media ecosystem operates this way. The criticism that bloggers weren't fit to sit side-by-side with the traditional media because it's just a bunch of unemployed losers writing in their underwear about what their cat had for breakfast was never fair to begin with.

But the ultimate irony is that many bloggers have more integrity and skill and are better journalists than the "real press" are today, and in so many cases it's not even close.

Mistakes this huge deserve a full retraction and an apology for misleading readers. Any bets on when -- if ever -- we see that?

Update
The title of the EW story best illustrates how much liberty they took with the truth: "Trey Parker and Matt Stone say they will definitely make a 'Book of Mormon' movie -- EXCLUSIVE"
