According to The Hollywood Reporter, director Ed Zwick has signed on to direct the adventure drama Diamond for Warner Bros. Pictures.

Formerly known as "Okavango," Diamond recounts the story of a poor African farmer who gets caught up in a conflict between an American diamond smuggler and the syndicate that controls the local diamond-mining industry, all in the path of one very valuable diamond.

Zwick and Bedford Falls partner Marshall Herskovitz rewrote the original script from Charlie Mitchell. Charles Leavitt also did a rewrite.

Zwick is attached to direct Happy Endings. He is the director of such films as The Last Samurai and Courage Under Fire, and his producer credits include Traffic and I Am Sam.
