Part 11/13:
Beyond props and set pieces, Darren highlights moments where character actions or details break continuity. For example, Marty finds Doc in the phone book, but the hand shown appears far too young, and pages are torn out inconsistently. The film’s depiction of Doc’s futuristic sunglasses also raises questions about their see-through quality, suggesting they might be non-functional or simply cosmetic.
Additionally, Marty’s skateboard, playing a vital role in the scene where he escapes in 1955, is noted as being more modern than what would have been available in that era, hinting at an oversight by set designers.
