Peter Coyote, currently on-screen in the Julia Roberts "Erin Brockovich" megahit, starts in "A Time For Dancing" next month. "It's a very exciting project," Coyote says of the film, which stars "Roswell" regular Shiri Appleby and Larisa Oleynik ("10 Things I Hate About You"). "It's the story of two girls who are best friends and totally committed to dancing; one of them gets cancer. I play her father."
