Richard Linklater, a filmmaker known for the whimsy of "Slacker" and "School of Rock," is planning a big-screen adaptation of "Fast Food Nation," the 2001 expose book by Eric Schlosser. Filming began Monday in Texas and will continue at locations there, in Colorado and Mexico. The preparations have had the secrecy of a stealth mission. A recent call to the production office requesting information about the movie provoked a crackling pause on the telephone line. The hesitant voice finally said, "You mean... 'Coyote'?" In September, The Austin American-Statesman reported that the drama, written by Mr. Linklater and Mr. Schlosser and starring Catalina Sandino Moreno ("Maria Full of Grace") is hiding under the sheep's clothing of a pseudonym. The false name - "Coyote" - was chosen, the newspaper said, to help the production gain access to franchise restaurants and other industry locations that might be off limits if the movie's true source material were known.
