Beginning with the 1959 explosion of “The 400 Blows” at the Cannes film festival, and ending with the politically charged rift post May ’68 that effectively disbanded the New Wave, filmmaker Emmanuel Laurent expertly compares and contrasts the films, friendship, and differences of titans Francois Truffaut and Jean-Luc Godard. Filled with clips of the films, and essential interviews from the period, and a refreshing lack of talking heads, this is catnip for the knowledgeable cinephile.
