The second full length (green band) trailer for Kevin Smith’s porntastic romantic comedy ZACK AND MIRI MAKE A PORNO recently hit the interwebs and though a lot of it is stuff we’ve seen before, there’s a few new things that should get you even more excited to see this flick. As the title so clearly explains, in the film, Seth Rogen and Elizabeth Banks as the titular lifelong friends make a porno in an attempt to get out of debt and realize boning only brings out their true feelings for each other.
