The King of the "mockumentary" is back, and this time he’s taking aim at retro collectors. Christopher Guest, the man behind Waiting for Guffman and Best in Show, is returning to his director’s chair, and he’s bringing along Harry Shearer and Michael McKean.

Guest, Shearer and McKean are putting their heads together to make a movie about the world of retro collectors; people who ferret out such things as old comic books, Barbie dolls, vintage magazine ads, vinyl 45-rpm singles, or even – ick! – Charles Manson song lyrics written on Kleenex. There’s a massive underground of collectors who would do the Borgia’s proud as they scheme and double-cross to possess the item they crave.

While there has been no confirmation that this is, in fact, a mockumentary, chances are high. If so, will it do as well as the Casey Affleck/Joaquin Phoenix mockumentary, I’m Still Here, which has grossed an estimated $259,290? Only time will tell. (WOW via MovieFone)
