The cast for writer-director David Wain’s new comedy Wanderlust is filling out and it’s been quite impressive. Wain co-wrote and directed Paul Rudd in Role Models, which I feel was the best comedy of 2008. Now Variety is reporting that Kathryn Hahn (Crossing Jordan, Step Brothers) will join Wain and Rudd in Wanderlust, and I can’t wait to see what wild antics she will undoubtedly have. Meanwhile, news about the World War I drama Four Saints from multi-talented Jean-Pierre Isbouts has arrived. Variety reports that Lorena Rincon, Rhona Mitra, Selma Blair, and Melanie Lynskey will topline the upcoming war drama written and directed by Isbouts. Hit the jump for further details on the cast of Wanderlust and what Four Saints is all about.

Wain has been slowly gathering a great cast around Wanderlust, as Hahn will join Rudd, Jennifer Aniston, Malin Akerman, Alan Alda, Justin Theroux, and Ray Liotta. This might be one of the first Aniston comedies that I am genuinely excited for, despite her high-profile role. Rudd and Aniston play a couple that look for a different way of life and leave behind the modern trappings of New York City and somehow land in a hippie commune (Hahn is a member of said commune). We reported earlier this month that Alda will be the head of a naturalist village, and I can only hope that Wain is shooting this with an R in mind. Apatow Productions is set to produce the film.

As for Four Saints, the film will adapt Isbouts’ own novel Angels in Flanders and center on four female nurses “who defied the British Army -- as well as German bombs and bullets -- to operate an illegal medical dressing station on the Allied front lines during World War I.” The quartet of actresses will join Cary Elwes and Arnold Vosloo. Principal photography is set to start in November for six weeks in Calgary, Alberta. White Wing Enterprises and Andrew Ferns will produce along with the help of Alberta Production Plan, Hollywood Wizard, and Structured Capital Group.
