Love and Other Drugs is based on the book Hard Sell: The Evolution of a Viagra Salesman and stars Jake Gyllenhaal and Anne Hathaway. Gyllenhaal plays a salesman who works in the weird world of pharmaceutical drugs and begins to find serious success by selling a new male performance enhancement drug. Gyllenhaal eventually meets Anne Hathaway's character during one of his sales calls and pretty much falls head over heals for her. Who wouldn’t? Mama is lookin' good.
