Nicky’s review published on Letterboxd :
There is something about the atmosphere in Two-Lane Blacktop that makes it stand out. The tribute to pure Americana in a changing society, the open roads and the urge for freedom; alone or with a companion.
James Taylor and Dennis Wilson are both very naturalistic in their portrayals and Hellman's choice to give them sparse dialog was a good choice. It brings out authenticity how these kind of aloof guys would be in real life. Being musical artists and not professional actors, it's like Taylor and Wilson perform their roles in the movie the same way they would do at a concert. As an extension of themselves rather than playing specific characters.
