Early work

In 1994, after graduating from San Francisco State University's film school,^[3][4] he started working with Jamie Hyneman at M5 Industries. Belleci worked as a stage manager, running errands and cleaning the shop, but quickly moved up the ranks. A few years later, he started work at Industrial Light and Magic (ILM). Belleci worked for ILM for eight years as a model builder, sculptor, and painter.^[5] Belleci began work on Discovery Channel's MythBusters in 2003, doing work behind the scenes and, in the second season, was featured as part of the show's build team. In the show's third season, he received on-screen credit.^[2] In 2005, Belleci persuaded fellow ILM veteran Grant Imahara to join the show, following the departure of original cast member Scottie Chapman.

Belleci worked on: the Matrix trilogy, Van Helsing, Peter Pan, Starship Troopers, Galaxy Quest and Bicentennial Man.^[6]

One of his short films, SandTrooper, has appeared on Syfy and in the Slamdance Film Festival.^[7]

MythBusters

Belleci is often considered by fellow MythBusters Kari Byron and Grant Imahara to be more of a daredevil and, as such, often performed the more dangerous stunts when testing a myth. These have included: testing the "Red Flag to a Bull" myth; testing the myth that a human's tongue will instantly stick to a frozen pole, in the "Snow Special" episode; and the myth "can you stay underwater for an hour while breathing through a dart tube?", in the "Ninja Movie Myths 2" episode. One of his more popular stunts, shown several times on the show, was an attempt to jump over a toy wagon on a bicycle; the attempt failed, resulting in Belleci flipping forward and landing on his face. The bike almost hit Belleci's head. As a result of doing these stunts, he is often involved in comical accidents while testing myths.^[2] According to the October 28, 2012, episode of MythBusters, he suffers from acrophobia.

During the "Hollywood Hang" sequence, of the 2010 episode "Soda Cup Killer", Belleci fell off a roof, and despite being strapped into a safety harness system, landed in an open window frame below the drop point, and injured his leg, causing substantial bleeding.^[8]

He and Byron made a guest appearance on the October 3, 2012, episode of the Discovery series Sons of Guns. They test-fired some of the weapons in the Red Jacket shop and watched as the staff re-tested a myth previously busted by the Build Team: that a propane tank could explode if struck by a bullet.

On August 21, 2014, it was announced that Belleci, along with his co-stars Byron and Imahara, would be leaving MythBusters.^[9]

In 2021, Belleci returned to host Motor MythBusters and was joined by engineer Bisi Ezerioha and mechanic Faye Hadley. The show focuses on tall tales about automobiles and last aired in March 2022.
