Silvestri agreed, despite a lack of experience: "I went out and bought a how-to-compose book by Earl Hagen.... At one point, I was using beer cans for percussion.

Since then, he has composed the music for all of Zemeckis's movies, including the Back to the Future trilogy (1985–1990), Who Framed Roger Rabbit (1988), Death Becomes Her (1992), Forrest Gump (1994), Contact (1997), Cast Away (2000), The Polar Express (2004), Beowulf (2007), A Christmas Carol (2009), Flight (2012), and The Walk (2015).

He has won the Saturn Award for Best Music three times, for his scores for Predator (1987), Back to the Future Part III (1989/90), and Van Helsing (2004).
