More than 20 years of televised reviews by newspaper film critics Roger Ebert, Gene Siskel and Richard Roeper are available at the Website AtTheMoviesTV.com.

The site calls itself the largest collection of video-based movie reviews online. It features about 5,000 lively discussions of movies that always end with the reviewers’ “thumbs up” or “thumbs down” evaluation.

Visitors can see just how often the Chicago Tribune’s film critic, and his counterpart at the Chicago Sun-Times disagreed on “Siskel and Ebert at the Movies.” They also can watch “Ebert & Roeper,” the newer version since Siskel’s death in 2000.
