Jack Black has joined Nicole Kidman and Jennifer Jason Leigh in Noah Baumbach’s untitled film for John Lesher’s Paramount Classics. Scott Rudin is producing.

Black will play the husband of a young woman who is visited at her upstate home by her sister and 12-year-old nephew. Baumbach’s script originally was titled “Nicole in the Country,” until that became too literal when Kidman committed.

Lesher made Baumbach’s follow-up to “The Squid and the Whale” one of his first major projects when he left his post as an Endeavor agent to run Par Classics.

Since arriving, Lesher also has set production starts for “There Will Be Blood,” an adaptation of the Upton Sinclair novel “Oil!” with Paul Thomas Anderson to direct and Daniel Day-Lewis to star, and “No Country for Old Men,” a Joel and Ethan Coen adaptation of the Cormac McCarthy novel to star Tommy Lee Jones and Javier Bardem. Rudin is producing both projects, and Lesher partnered in each with Miramax’s Daniel Battsek.

Lesher’s is the sole studio on the Baumbach film.

Coming off “King Kong,” Black just completed the Nancy Meyers-directed “The Holiday,” which Col opens Dec. 8. Next out is “Nacho Libre” on June 2, followed by “Tenacious D in The Pick of Destiny,” which New Line releases Nov. 17.
