Campbell Scott has been signed to direct and star in a bigscreen version of Joan Didion’s 1977 novel “A Book of Common Prayer.”

Pic will be produced by Opaque Prods. in association with CoTreat Prods. Marcia Weiss is producing; Joyce McKee and Rachel LeMin did the adaptation.

Lensing will begin this fall in Puerto Rico. Story centers on two American women whose paths cross in a fictional Central American country on the verge of revolution: One married into one of the families that dominate politics in Boca Grande; the other has seen her marriage fall apart and her daughter run off with a group of Marxist radicals.

Scott’s directing credits include “Off The Map,” “Final” and “Company Retreat”; he also co-directed “Big Night.” Scott was last seen in “The Amazing Spiderman” as Richard Parker.

Scott is represented by Paradigm.
