Hawke and Dano - who've both received accolades recently for the film First Reformed and the Showtime series Escape at Dannemora, respectively - do an excellent job going round for round, playing into the comedic moments of their fighting, and director James Macdonald gives the play a cinematic touch by using music and a picture-frame effect of bright lights around the stage between scenes. (The costumes, by Kaye Voyce, get more disheveled as the action ramps up.) But while watching them go at it is entertaining, what the play is fighting for isn't as clear. There are themes of sibling rivalry and family strife (their father, unseen but spoken of, is a drunk living alone out in the desert), the idealized lawlessness of the Wild West, the way Hollywood deals are done and just as easily undone. But all those questions are left unanswered, with strewn beer cans and dead plants to show for all the debate.
