Twin Cities voice-over and radio actors, Tim Russell and Sue Scott, have a busy summer of filming ahead of them. As regular PHC cast members, Russell and Scott will appear, along with stars Meryl Streep, Lindsay Lohan and Woody Harrelson, in Robert Altman’s new movie, a fictionalized film version of Garrison Keillor’s legendary radio variety show, “A Prairie Home Companion.” The premise of the film is that Keillor’s award-winning show is mysteriously canceled after 30 years on the air. As the ensemble of radio actors, musicians and back-stage crew prepare for their final live broadcast, old passions, feuds and grievances surface as their imperious stage manager (Tim Russell) tries to hold the radio show’s motley cast and crew together. Garrison Keillor, who has written the script, will play himself in the Robert Altman movie. Also confirmed are John C. Reilly, Lily Tomlin, Kevin Kline and Maya Rudolph. The movie will begin shooting in July at the Fitzgerald Theater and at Mickey’s Diner in St. Paul, Minnesota.
