Zack and Miri make porno Wallpapers

Lifelong friends and roommates Zack (Seth Rogen) and Miri (Elizabeth
Banks) are facing hard times and a mountain of debt. When the
electricity and plumbing get cut off, they seize upon the idea of
making a homegrown porno movie for some quick cash, enlisting the help
of their friends. The two vow that having sex will not ruin their
friendship. But as filming begins, what started out as a business
proposition between friends turns into something much more.
