Peter Scanavino

In 2005, Scanavino guest-starred on the NBC crime-drama series Law & Order: Criminal Intent in the fifth-season episode "Diamond Dogs" as petty criminal Johnny Feist. He was also a guest on Law & Order as a suspect who was a graphic designer in the 2009 episode "Just A Girl in the World".

In 2013, Scanavino guest-starred on the long-running NBC crime-drama series Law & Order: Special Victims Unit in Season 14, Episode 13, "Monster's Legacy", as Johnny Dubcek. The same year, he starred in the independent romantic-comedy film Mutual Friends, directed by Matthew Watts.

In 2014, Scanavino joined SVU in its sixteenth season, this time as Dominick Carisi Jr., nicknamed Sonny, a new SVU detective. Initially in a recurring capacity, Scanavino was promoted to the main cast in the fifth episode of the same season. According to SVU Executive Producer Warren Leight, Carisi "comes in and shakes things up" and is "a guy who maybe needs a little bit of refining." Scanavino noted that Carisi is "a total outsider. He's brusque and he doesn't really get the nuances and he's not very experienced so he puts his foot in his mouth a lot of times. But he's learning. He's picking it up. I think he's a good detective, but he's got a lot to learn on how to approach cases."

Scanavino starred in an episode of Netflix's 2020 anthology series Social Distance as the father of his real-life son Leo Bai-Scanavino.
