According to The Hollywood Reporter, actor Jeremy Piven is stepping into a leading role after nearly two decades of supporting roles. Piven is in final negotiations to star in New Line Cinema's untitled man vs. nature project being produced by Robert Simonds.

Piven became a breakout performer with HBO's Entourage, on which he plays Hollywood superagent Ari Gold -- the role earned him a Golden Globe nomination and an Emmy nomination -- and the deal will mark the first starring, above-the-title credit in his career. In the nature project, Piven will play a smug Portland, Ore., real estate developer who accepts a challenge from his real estate mogul boss to develop a pristine forest in the hopes of being promoted to partner. He gets more than he bargained for when the area's animal residents start taking their revenge on him and wreak havoc on his every attempt to develop the land.
