Meryl Streep, Lindsay Lohan and Woody Harrelson are set to star in Robert Altman’s next movie, a spinoff from Garrison Keillor’s radio variety show “A Prairie Home Companion.” Keillor has written the script and will appear as himself in the movie, to shoot this summer in Minneapolis. John C. Reilly, Lily Tomlin and Maya Rudolph are also confirmed to star, with Kevin Kline in talks to join the cast. The film is based on the fictionalized premise that Keillor’s award-winning show, which is carried on 500 radio stations across the States, is being shut down after 30 years. As the ensemble of performers, musicians and backstage crew prepare for the final live broadcast, long-simmering passions boil to the surface while an imperious stage manager struggles to hold everyone together. Streep and Tomlin play sisters, while Lohan is a sexy ingenue. A menacing stranger, who may just be the angel of death, stalks in the wings, but the show must go on.
