It may seem like having a child protagonist might restrict the themes and subject matter that you would explore, but just take a quick look through an array of films of this kind to see the depth that’s possible: Louis Malle’s Au Revoir Les Enfants (a favorite of Branagh’s) handles the shame and complicity of bystanders during the Holocaust, Spike Lee’s Crooklyn celebrates a Brooklyn childhood without once losing perspective of race and class, Terrence Davies’ The Long Day Closes is a blossoming poem to the childhood memories that we carry with us for life, Abbas Kiarostami’s Where is the Friends House?
François Truffaut may have started off with “The 400 Blows,” but typically films like Federico Fellini’s “Amarcord,” Woody Allen’s “Radio Days” and Spike Lee’s “Crooklyn” arrive a little later in the careers, after they're lauded enough to start feeling reflective.
