'Love and Other Drugs' finds brother

Josh Gad joins Jake Gyllenhaal, Anne Hathaway in cast

Actor/comedian Josh Gad has joined Jake Gyllenhaal and Anne Hathaway in the business-world drama "Love and Other Drugs" at Fox 2000/New Regency.

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.

Zwick and his Bedford Falls partner Marshall Herskovitz are producing along with Scott Stuber, who originated the project. Randolph is also producing.

Repped by ICM and Urge Artists, Gad appears regularly as a news correspondent on Comedy Central's "The Daily Show." His film credits include "21," directed by Robert Luketic, as well as "The Rocker," Fox Atomic's comedy starring Rainn Wilson.
