Gerry O'Hara's journey in the film industry commenced while he was a journalist for the Boston Guardian, where he secured his first break in the industry. During his time as a reporter, he was assigned to interview Michael Powell, who was filming One Of Our Aircraft Is Missing in the local area. This encounter had a profound impact on O'Hara, as it inspired him to take the initiative and write to Powell, requesting a job in the film industry.
Miraculously, Powell responded to O'Hara's letter, leading to his first job in the film industry as a trainee in the script department at Verity Films. Over the course of the next few years, O'Hara worked on a variety of Ministry Of Information films, gradually working his way up the ranks to become an assistant director.
Throughout his career, O'Hara had the privilege of collaborating with some of the most renowned directors in the industry, including Otto Preminger, Carol Reed, Ronald Neame, Tony Richardson, and Laurence Olivier. In 1963, he was given the opportunity to direct his first film, That Kind Of Girl, marking the beginning of his directorial career.
O'Hara's directorial credits continued to grow, with his last film being the horror movie The Mummy Lives, released in 1993.
