 This is the Turner Classic Movies (TCM) cable channel s 13th annual "31 Days of Oscar" festival. For the entire 31 days, each of the feature films and short subjects is a winner or nominee of at least one Academy Award. This year, the focus is on the Oscar categories. Generally, each day showcases nominees and winners of an individual category (the films may have been nominees or winners in another category as well). Films featuring most categories (e.g., Art Direction, Costume Design, Film Editing) are shown for 24 hours. For other categories, the time frame differs. For example, the Foreign Language Film nominees and winners were shown from 6pm on 4 February to 6am on 5 February (12 hours), while a 48-hour Best Picture winners marathon ran from 6pm on 22 February through 6pm on 24 February. For each acting category, 24 hours of films were devoted to nominees, followed by 24 hours of winning performances.
