Jake Gyllenhaal and Anne Hathaway back together for “Love”

Jake Gyllenhaal and Anne Hathaway are in negotiations to reunite for “Love and Other Drugs.

Ed Zwick is directing the project (formerly titled “Pharma”), which Charles Randolph (“The Interpreter”) adapted from Jamie Reidy’s nonfiction book “Hard Sell: The Evolution of a Viagra Salesman.”

Reidy was a drug rep for Pfizer in the late 1990s who eventually wrote a memoir that shined a light on the practices of the pharmaceutical industry. Gyllenhaal will play the salesman, who begins a relationship with a woman who has Parkinson’s (Hathaway) while on one of his sales calls. Their love story plays out in the political and social context of the time.

Gyllenhaal and Hathaway previously worked together in Ang Lee’s “Brokeback Mountain”, playin a doomed husband and wife.
