Jim Sharman's early life was deeply rooted in the world of entertainment, as his father and grandfather operated a traveling boxing sideshow within a circus. This unique upbringing fostered an early interest in the performing arts, which eventually led him to pursue a formal education in theatre at the National Institute of Dramatic Art in Sydney. Upon graduating in 1966, Sharman's passion for experimental theatre began to take shape, and he started to make a name for himself in the industry.
It was during his direction of the Sydney production of Hair in 1970 that he crossed paths with a young architectural student named Brian Thomson, who would later become his trusted set designer. Their collaboration proved to be a fruitful one, and together they brought a local production of Jesus Christ Superstar to the attention of renowned lyricist Tim Rice. Rice was so impressed with their work that he invited Sharman and Thomson to London in 1972 to stage a production of the show, which featured a young Richard O'Brien.
The success of their London production of Jesus Christ Superstar ultimately led to Sharman being approached to direct the stage production of The Rocky Horror Show. This experience not only allowed him to hone his craft but also provided the opportunity to direct the film adaptation, The Rocky Horror Picture Show, in 1975, as well as its sequel, Shock Treatment, in 1981. Throughout his illustrious career, Sharman established himself as one of Australia's most respected theatre directors, leaving a lasting impact on the world of entertainment.
