Actor/comedian Josh Gad has boarded the business-world drama Love and Other Drugs, joining Jake Gyllenhaal and Anne Hathaway in the Fox 2000/New Regency feature.

According to The Hollywood Reporter, Ed Zwick (Defiance) 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."

The story follows a salesman (Gyllenhaal) who competes in the cutthroat world of pharmaceuticals to hawk a male performance enhancement drug and enters into a relationship with a woman (Hathaway) with Parkinson's disease. Gad has been cast as Gyllenhaal's brother, a vulgar but successful dot-com entrepreneur who moves in with Gyllenhaal.

No production date has been set.
