Growing up in the shadow of New York City, Joseph Mazzello got into acting at a young age, making his first appearance at the age of 7 in the Harrison Ford-starring "Presumed Innocent" (1990). He followed that up with a succession of films featuring directing and acting legends, most prominently as one of the children from Steven Spielberg's "Jurassic Park" (1993). He also worked with Richard Donner in "Radio Flyer" (1992), Anthony Hopkins in "Shadowlands" (1993), and Meryl Streep in "The River Wild" (1994). He returned to Jurassic Park for a brief appearance in "The Lost World" (1997), but then slowed down his burgeoning acting career by going to University of Southern California to study film. After graduation and some time exploring writing and directing, his next big role was the lead in the Spielberg-produced World War II miniseries "The Pacific" (HBO 2010). The same year, he also had a major role in the acclaimed David Fincher film "The Social Network" (2010) as Dustin Moskovitz. Over the next few years, Mazzello was active across a number of projects, including appearances in "Justified" (FX 2010-15), "Person of Interest" (CBS 2011-16), and "Elementary" (CBS 2012- ) as well as a role in "G.I. Joe: Retaliation" (2013). He portrayed Queen's bassist John Deacon in the Rami Malek-starring biopic "Bohemian Rhapsody" (2018).
