Film fans, start your check-writing. On his blog late Sunday, famed critic Roger Ebert revealed that his television show, 'Ebert Presents At the Movies,' will go off the air in January if further funding cannot be found. Wrote the venerable critic: "Unless we find an angel, our television program will go off the air at the end of its current season. There. I've said it. Usually in television, people use evasive language. Not me. We'll be gone. I want to be honest about why this is. We can't afford to finance it any longer."
