3. Anchorman 2 (9.5 years)
Previous Release: Anchorman, released July 2004.
The Sequel: Anchorman 2: The Legend Continues, due out December 2013. It takes a very special kind of comedy to even manage to build enough momentum to earn a sequel so long after the fact, but cult classic Anchorman has somehow managed it, with the sequel coming out just shy of a decade after the original movie hit cinemas. This, like Sin City 2, is a film that has been talked about for so long that the idea of the film actually ever coming out had become nothing more than a distant prospect to most. We had all but given up hope of it ever being made, what with the constant jostling between a hopeful Will Ferrell and months without hearing a word. The problem is that Anchorman 2 has so much to live up to that it's best to just tune out the hype, set your expectations to middling and hope for the best; then you might be pleasantly surprised.
