As it is, American Vampire is a bomb. It's not funny, it's not scary, and it's not interesting enough to recommend. The producers know this -- which is why they added to the rather standard DVD something they call a "comedic audio track." Two film-savvy comedians (Brian Palermo and Sean Hogan) from the L.A. comedy troupe the Groundlings candidly -- and hilariously -- make fun of the film during their feature-length commentary. They make fun of the wooden actors, the awful dialogue, a houseplant that has way too much screen time, wayward continuity, visible microphones and, most importantly, they chide the filmmakers for not exploiting Carmen Electra, who plays a sexy bisexual vampire who does little more than loll seductively and lick her lips. In addition to the CAT -- which is engineered so that viewers can hear the dialogue at the same time -- the disc includes interactive menus, theatrical trailers (ironic, in that the film never played in theaters), text filmographies, and subtitles. But no laughs, except for the CAT.
