A John Doyle-helmed stage adaptation of “The Exorcist” and world-premiere plays by Alan Alda and Beth Henley are on tap for the 2011-12 season at L.A.’s Geffen Playhouse.

“Agnes of God” playwright John Pielmeier adapts William Peter Blatty’s 1971 novel, also the inspiration for the famous 1973 horror pic. Production from director Doyle (“Sweeney Todd”), whose Rodgers-Hart catalog tuner “Ten Cents a Dance” will be seen at the Williamstown Theater Festival this summer ahead of a run at the McCarter Theater, is slated to play July 3-Aug. 12, 2012.

Prior to its run at the Geffen, the new play by Alda — science bio-drama “Radiance: The Passion of Marie Curie” — will be seen in a starry reading as part of the World Science Festival in Gotham. Meryl Streep, Amy Adams, Allison Janney, Liev Schreiber and David Morse are among the thesps lined up for that initial reading June 1. Cast, helmer and exact date for the Geffen incarnation remain to be nailed down.

Henley’s latest, “The Jacksonian,” centers on a spooky motel on the night of a murder. Robert Falls, a.d. of the Goodman Theater in Chicago, helms the staging that runs Jan. 31-March 11.

Also on the season slate is Kathleen Turner vehicle “Red Hot Pariot: The Kick Ass With of Molly Ivins” as well as west coast preems for two Gotham alums, Kristoffer Diaz’s “The Elaborate Entrance of Chad Deity” and “Next Fall.”

One spot remains open in the Geffen lineup, with a title to be solidified later.
