Inspired by muscleman actor Steve Reeves, Rick Cassidy (born Richard Edward Ciezniak Jr. in Lackawanna Pennsylvania) decided he wanted to become a professional bodybuilder at age 14. After a stint in the Navy, he competed in bodybuilding competitions and quickly moved from that to physique modeling, which led to a career in hardcore adult features, both gay and straight. He appeared in around 100 adult features and sex loops in total plus made the occasional non-XXX film appearance, including the Ed Wood-scripted troika of Drop Out Wife (1972), The Beach Bunnies (1976) and Hot Ice (1977). Cassidy also featured in the twisted sex-heavy horror flicks Sex Psycho! (1970) and Evil Come Evil Go (1972), the Australian softcore comedy Fantasm Comes Again (1977), the early Charles Band production Auditions (1978) and the X classic New Wave Hookers (1985). He permanently retired from film in the mid 80s and moved back to his home state where he worked as a real estate agent. He passed away in 2013 at age 70.
