Seth Green (born Seth Benjamin Gesshel-Green on February 8, 1974; 44 years old) is an American actor and voice actor best known for his work on Robot Chicken and Family Guy.

He replaced Jason Biggs and Dominic Catrambone as Leonardo in the third season of the 2012 TV series.[1]


  • Green took the role because his wife's favourite Turtle is Leonardo, and he wanted to play a character his wife already had 'the hot's for'. At this, Rob Paulsen said that it was 'very convenient'.
