So, on August 21, Magnolia Pictures will start taking Bobcat Goldthwait's pitch-black comedy, World's Greatest Dad, to theaters nationwide. (Disclosure: our sister company, Cinetic Media, co-repped the film at Sundance along with CAA.) Like many Magnolia titles, though, this one is already available to eagers audiences via Cable VOD. Plus, following in the footsteps of other Magnolia pre-release VOD debuts, the film is also available on Amazon right now. So, you can wait a few more weeks and maybe it will come to a theater near you, or you can rent it on Amazon from the comfort of your computer now, for less than the price of one ticket. Amazon VOD titles can also be viewed/rented through a Roku player, a TiVo box, and now the Panasonic Blu-Ray DVD and HDTV machines. So, you can start quoting some of the film's infamously funny lines before the rest of the world catches on.
