A new teaser site for an upcoming Garfield film can be found here. Though the site includes the date “2009”, it does not provide any other clues as to what the project could be about, so as of now it is unknown as to whether or not it will be a DTV or theatrical release. However, similarities between the site and Garfield’s Pet Force point to an adaption of the spin-off series. Thanks to Josh for the link.
