Early life

Mazzello was born in Rhinebeck, New York, and raised in Hyde Park, New York, the son of Virginia (née Strong) and Joseph Mazzello, Jr., who owned a performing arts school. He has one older sister, Mary, and a younger brother, John, who have both appeared in films. His father is of three quarters Italian and one quarter German Jewish ancestry, while his mother is of Irish, Polish, and English descent. Mazzello went to Catholic school Our Lady of Lourdes. He is an alumnus of the University of Southern California, entering the USC School of Cinematic Arts in 2001 following a recommendation letter of director Steven Spielberg. Mazzello paid for school with his salary from a small appearance in The Lost World: Jurassic Park (1997), something the actor jokingly referred to as "my graduation present from Spielberg".

Career

Mazzello's first film appearance was a small role in Presumed Innocent (1990), starring Harrison Ford. He followed up that success with a supporting role as an abused child in the drama Radio Flyer (1992). His most notable roles were as Douglas Gresham in Shadowlands and Tim Murphy in Jurassic Park, both in 1993, Dexter in the 1995 film The Cure, and Eugene "Sledgehammer" Sledge in the HBO miniseries The Pacific. In 2010, Mazzello played Dustin Moskovitz, one of the co-founders of Facebook in the David Fincher-directed film The Social Network.

Mazzello's directorial debut was made with the short film Matters of Life and Death (2007) in which he also stars; the cast includes David Strathairn (with whom he has worked in The River Wild (1994), Simon Birch (1998), and The Sensation of Sight (2006)), Daniel Gillies, and Rachael Leigh Cook.
