John Calvin Culver (November 2, 1943 – August 10, 1987), better known under his stage name Casey Donovan, was an American male pornographic film actor from the late 1960s until the mid-1980s, appearing primarily in adult films and videos catering to gay male audiences, during the Golden Age of Porn. Following a brief career as a Latin teacher and a stint as a highly paid male model, Donovan appeared in Boys in the Sand (1971), the film that would cement his status as a gay icon. Attempts to build on his notoriety to achieve mainstream crossover success failed, but Donovan continued to be a bankable star in the adult industry for the next 15 years. He was briefly a mainstream actor, who appeared on stage, as well as a theatre producer and manager and appeared as himself in TV series Emerald City. Early life Culver was born in East Bloomfield, New York, growing up there with his parents and older brother Duane. Culver attended the State University of New York at Geneseo (SUNY), where he was a member of Phi Sigma Epsilon fraternity and the drama club. After graduation in 1965 he accepted a teaching position in Peekskill, New York. He later took a job at the private Ethical Culture Fieldston School on New York City's Central Park West but was fired during his second year following an altercation in which he physically disciplined a female student (reportedly the daughter of actor Eli Wallach). Following his dismissal, Culver drifted into prostitution. He also began pursuing an acting career, appearing in summer stock theatre with the Peterborough Players. Modeling career Through one of his escorting clients, Culver landed a spot with the Wilhelmina Models modeling agency, commanding an hourly rate of US$60 (equivalent to $400 in 2020). He continued to pursue stage work, landing an understudy job in 1969 in the Off-Broadway gay-themed play And Puppy Dog Tails, making his Broadway debut in 1970 in the Native American-themed production Brave and a co-starring role in the off-Broadway play Circle in the Water (also in 1970). Adult film career In 1971, Culver played a supporting role in a low-budget sexploitation thriller film called Ginger. While the film was a commercial and critical failure, Variety noted his performance positively, saying "Only Calvin Culver ... shows any indication of better things to come." This in turn led to an offer to appear in Casey,
