*”Parks and Recreation” star Rashida Jones will join Elizabeth Banks, Zooey Deschanel and Emily Mortimer opposite Paul Rudd in the big screen comedy “My Idiot Brother.”

The story centers on an idealist (Rudd) dealing with his over¬bearing mother who crashes at the homes of his three ambitious sisters and brings truth, happiness and a sunny disposition into their lives while also wreaking havoc. Banks, Deschanel and Mortimer will play the sisters.

Banks plays a career-driven single about to get her big break in journalism after spending years writing about accessories at a fashion magazine; Deschanel is a bisexual whose flakiness and lies are getting in the way of moving forward with her caring, responsible girlfriend (Jones); and Mortimer plays a Park Slope mom too worried about having the perfect life and children to notice that her marriage is falling apart.

The comedy is being directed Jesse Peretz and produced by Anthony Bregman’s Likely Story and Big Beach’s Peter Saraf and Marc Turtletaub.

Jones recently wrapped David Fincher’s “The Social Network.”
