Don’t have time to complete a Film Studies class? This video by Patrick Willems gives one a better overview in 11 minutes than your average academic lecture could. (You can disregard everything about the Marvel movies and color grading in the beginning.)
Bonus? Check out this video essay by Kogonada for the BFI’s Sight & Sound comparing Vittorio De Sica’s Terminal Station and David O. Selznick’s Indiscretion of an American Wife.
