Dr. Black, Mr. Hyde

Dr. Black, Mr. Hyde is an intriguing 1976 horror film directed by the legendary William Crain, with an enticing screenplay by the renowned Larry LeBron and Lawrence Woolner. Filling the starring roles are Bernie Casey, Rosalind Cash, and Marie O’Henry. Injecting a fascinating blaxploitation twist into the classic Robert Louis Stevenson tale, the movie explores themes of race, identity, and morality, all the while enrapturing its audience with a compelling narrative and a uniquely layered titular character.

In this film, Bernie Casey takes on the role of Dr. Henry Pride, a dedicated, charismatic, and brilliant medical practitioner working persistently in an underserved and largely impoverished urban area. Dr. Pride is genuinely committed to his pursuit of medical advancements aimed at improving the health conditions of his community. Being an African American scientist who has risen above societal prejudices, Pride embodies the struggle for justice and equality, while his medical aspirations reflect a more personal pursuit of absolution.

Dr. Pride’s tireless research leads him to develop a groundbreaking serum intended to reverse liver damage. The ambitious doctor’s sincere intentions, however, soon give way to an unexpected dark turn, leading the narrative along a path mirroring the iconic Dr. Jekyll and Mr. Hyde tale. After testing the experimental serum on himself, he undergoes a horrifying transformation, not into a pallid covert like the original Stevenson’s Mr. Hyde, but instead, into the towering, monstrous figure of a white-skinned bald man with red eyes.

Co-star Rosalind Cash steps into the shoes of a social worker named Linda, who works closely with Dr. Pride. Linda's character arc promotes a strong female presence in the narrative, illustrating a blend of compassion, courage, and independence. Linda and Dr. Pride's professional relationship takes a personal turn, adding a romantic subplot to the narrative, whilst alongside escalates Dr. Pride's internal conflict, now heightened by his disturbing physical transformations following the serum intake.

On the other hand, Marie O’Henry, playing a local resident's role, contributes to the narrative by depicting the direct impact of socio-economic conditions upon individuals, while also fleshing out Dr. Pride's character, shedding more light on his motivations and intentions.

Setting the movie apart is its masterful use of horror and science fiction elements as the film delves into the psychological complexities of Dr. Pride. Placed within the backdrop of racial issues, the movie lends a new spin to this genre, exploring facets not often examined in contemporary blaxploitation flicks of the 70s.

However, the essence of Dr. Black, Mr. Hyde lies in its contentious play on the theme of identity, as Dr. Pride grapples with his transformation into a horrifying alter-ego - a metaphorical manifestation of society's discriminatory views, fears, and prejudices. This is prominently showcased in the contrast between his altruistic demeanor as a doctor and his monstrous persona post transformation, a stark resemblance to societal misconceptions and stereotypes of African-American men at the time.

The film might be classified under horror, but it’s not just about shocks and scares. It goes beyond the trope-infused world of shrieks and gore to explore kindness, humanity, and the problematic notion of viewing people through the lens of color. At the heart of it, the narrative lands squarely on themes of racial stereotyping, classism, and the effects of both on one's identity.

On a technical level, the film boasts of remarkable cinematography for its period, with well-placed and atmospheric lighting that ramps up the suspense and unease. The haunting musical score further complements the eerie, chilling essence of the narrative.

Dr. Black, Mr. Hyde is a mesmerizing amalgamation of classic horror and modern societal commentary that successfully adapts Stevenson’s tale in a fresh and relevant context. It serves as a critical conversation starter on being black in America, living between dual identities, which continues to be relevant even today.
