Anna Mastro is a director whose work, while perhaps not yet boasting a sprawlingography, has already carved out a niche for itself among discerning physical media collectors. Her feature debut, *Walter* (2015), remains a notable entry point into her emerging style. This unique coming-of-age story, starring Andrew J. West as a young man who believes he is the son of God, has garnered a cult following for its quirky charm and introspective narrative. Collectors appreciate *Walter*'s distinctive tone, which often lands it on "hidden gem" lists for those seeking out offbeat independent cinema on DVD or Blu-ray. The film's limited theatrical run and subsequent life almost exclusively through home video have made it a sought-after title for collectors interested in supporting and preserving modern independent features. Mastro's direction in *Walter* showcases a keen eye for character and a willingness to explore unconventional themes, qualities that promise a compelling filmography for future collecting. As her career continues to evolve, early releases like *Walter* are poised to become even more valuable touchstones for those tracing the trajectory of an emerging directorial voice.
