(written from a Production point of view)
After working as a talent agent, Nardino held positions as Vice President in charge of the television departments at the Ashley-Famous Agency (now ICM Partners) and William Morris Endeavor (where he previously worked as an agent) during the 1960s and 1970s. In 1977, he was named President of Paramount Television. During this time, he oversaw production on highly successful television series such as Happy Days (starring Don Most), Taxi (starring Search for Spock actor Christopher Lloyd), and Cheers (starring Kirstie Alley), as well as mini-series and TV movies like Shogun (starring John Rhys-Davies and W. Morgan Sheppard), A Woman Called Golda (starring Leonard Nimoy and produced by Harve Bennett), The Winds of War (featuring Peter Brocco, Michael Ensign, Ken Lynch, Byron Morrow, George Murdock, Lawrence Pressman, and Logan Ramsey).
In 1983, Nardino formed his own firm, Gary Nardino Productions, in affiliation with Paramount. Besides Star Trek III, the only other film he for Paramount Pictures was the 1986 drama Fire with Fire, which featured Star Trek: Voyager performers Virginia Madsen and Tim Russ and editing by Peter E. Berger. During his final year at Paramount Television, he executive produced the short-lived series Marblehead Manor, which starred Phil Morris.
In 1988, he became chief executive officer at Orion Pictures (where he supervised such productions as Bill & Ted's Excellent Adventure) and he later became co-president at North Hall Productions and an executive at Warner Bros. Television, for which he produced the science fiction series Time Trax and the police series Pacific Blue. It was while working on the latter series that Nardino died from complications of a stroke in 1998.
