Before building his behind-the-scenes career, Rosenstein appeared in several films as an actor. He had a small role as Logan in the 1976 remake of King Kong and played an orderly in Winter Kills (1979).1 He took an uncredited role as The Monk in the science-fiction comedy The Ice Pirates (1984), and later appeared as a Protest Leader in License to Drive (1988).1 His on-screen work throughout this period overlapped with the early stages of his production career, and he continued to take the occasional small acting part alongside his crew work into the late 1980s.
His behind-the-scenes career began in location management. He served as Location Manager on several productions in the mid-1980s, including Fletch (1985) and, in 1986, three features in the same year: The Golden Child (directed by Michael Ritchie), About Last Night... (directed by Edward Zwick), and Wildcats (directed by Michael Ritchie again).1 The volume of work in that single year established him as a busy presence in Los Angeles-based production.
By the late 1980s Rosenstein had moved into assistant directing, a role that works closely with the director to manage scheduling and day-to-day set operations. He served as Second Second Assistant Director on Ivan Reitman's Twins (1988), his first documented collaboration with Reitman.1 That relationship continued directly into Ghostbusters II (1989)2 and then into Kindergarten Cop (1990), on which he held the more senior credit of Second Assistant Director, while also serving simultaneously as Location Manager on that same film.1
He worked as Second Second Assistant Director on William Friedkin's The Guardian (1990) and as Second Assistant Director on Ghost Dad (1990), Police Story: Gladiator School, and television work on The Young Riders. By 1992 he had advanced to Second Unit First Assistant Director on Beethoven,1 then to First Assistant Director on Beethoven's 2nd (1993).3 He received an Additional Second Assistant Director credit on Ivan Reitman's Junior (1994),1 completing what was a recurring working relationship with Reitman spanning six years.
In the mid-1990s Rosenstein moved into production supervision and location management on larger studio productions. He served as Production Supervisor on Star Trek: First Contact (1996, directed by Jonathan Frakes), one of the highest-profile credits of his career,3 and as Location Manager on Waterworld (1995) and Space Jam (1996).1 His television credits during this era include location work on Moonlighting and The Dukes of Hazzard.
In the 2000s he transitioned toward producing and unit production management. His credits include Visual Effects Production Manager on Rock Star (2001),3 Location Manager on Hidalgo (2004, directed by Joe Johnston), and Unit Production Manager on several independent features including The Last Run (2004), on which he also received an Associate Producer credit.3 His earlier UPM credits include Fish Without a Bicycle and Good-Bye Cruel World.
On Ghostbusters II (1989) Rosenstein is credited in the film's production credits as one of two Second Second Assistant Directors, alongside Cyd Adams,4 under First Assistant Director Peter Giuliano.2 His full name, Ira Stanley Rosenstein, appears in both the film's screen credits and in the official production press kit released by Columbia Pictures.24
In addition to his crew role, Rosenstein made an uncredited on-screen appearance in the film as a character identified in production materials as Stage Manager.1
