This British born executive began his career in 1962 when he joined Associated British Cinemas (the forerunner of EMI) as an assistant manager in exhibition. Two years later, Gibson began a ten- year association with the commercial distribution firm of Pearl & Dean.

By 1975, Gibson had moved to Los Angeles and worked as a producer for Sandy Howard Productions and spent one year as head of production at Astral Bellevue Pathe in Canada. Returning to the US, Gibson joined Hemdale Film Corporation in 1982 as head of production, eventually becoming its president.
